Electric potential and electric field are similar because their relationship are dependent oneach other. Electric potential is a part of the field that is describing what the field is doing. The biggest way that they differ is because electric field is a vector quantity, where electricpotential is a scalar quantity.
The key difference between these two quantities is that electric field is a function of position (and time), whereas the electric force applied by an electric field is associated with a particular object.Aug 20, 2021

Gravitational force is proportional to the masses of interacting objects, and the electrostatic force is proportional to the magnitudes of the charges of interacting objects. Hence both forces are proportional to a property that represents the strength of interaction for a given field.
In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.
To derive a relation between electric field and potential, consider two equipotential surfaces separated by a distance dx, let V be the potential on surface 1 and V-dV be the potential on surface 2. Let E be the electric field and the direction of the electric field is perpendicular to the equipotential surfaces.
Electric Potential is the work done per unit charge in order to bring the charge from infinity to a point in electric field while Electric potential difference is the Potential developed while moving a charge from one point to another in the field itself.Apr 28, 2021
Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.
electric field, an electric property associated with each point in space when charge is present in any form. The magnitude and direction of the electric field are expressed by the value of E, called electric field strength or electric field intensity or simply the electric field.
a. In both drawings I and II the electric field is the same everywhere. This statement is false. By inspection, we see that the field lines in II get closer together as we proceed from left to right in the drawing; hence, the magnitude of the electric field is getting stronger.
Electric fields are produced by stationary charge particles and varying magnetic fields. So, neutral particles cannot create electric fields. A gravitational field, on the other hand, is a model which is used to explain gravitational phenomena of masses. Even though neutral particles such as neutrons do not interact via electromagnetic forces, they do via gravitational forces. This is the main difference between electric field and gravitational field. This article tries to describe the difference between electric field and gravitational field in detail.
The gravitational field is the force field in gravitational interaction which is a model used to explain and understand gravitational phenomena. In classical mechanics, the gravitational field is a vector field. Several quantities such as gravitational field strength, gravitational force, ...
Electric fields are produced by electric charges or varying magnetic fields. Unlike charges (negative and positive charges) attract each other, like charges (negative- negative or positive- positive) on the other hand, repel.
In physics, an electric field is a model used to explain or understand the influences and behaviors of charges and varying magnetic fields. In this model, an electric field is represented by field lines. Electric field lines are directed towards negative charges whereas they are directed outwards from positive charges.
However, it is accurate enough to be used in most of the practical applications. When dealing with high gravity problems, general relativity must be used. In low gravity, it is approximated to Newtonian theory. Field of a positive electric charge in front of a horizontal perfectly conducting metal surface.
However, the Maxwell’s equations describe both electric and magnetic fields as a function of charges and currents. So, Maxwell equations are very useful when dealing with electric and magnetic fields. Gravitational field lines (black) and equipotentials around the Earth.

Even though we feel that gravity is a very strong force because we live our lives very close to the surface of the Earth, the electric force is actually much stronger.
Because there is only one kind of mass , gravitational forces are always attractive forces. Gravity will only make objects fall down toward the Earth. It will never cause objects to be repelled away from the Earth. If this were not true, you would see objects suddenly rising into the air without anything touching them.
When you hold up a ball and let it go, you know it will fall to the ground. You can also look up in the sky at night and see the moon pass overhead. A long time ago, a scientist named Isaac Newton wondered what was making both of these things happen, and he determined that the exact same force that makes the ball fall also keeps the moon in orbit around the Earth. He called this force gravity, and he showed that it's not only the Earth that creates gravitational forces. In fact, all objects with mass exert gravitational forces on each other. That means everything that has mass (including you) exerts a gravitational force on every other object with mass.

Newton determined that the gravitational force exerted between any two objects with mass is directly proportional to the mass of the two objects and inversely proportional to the square of the distance between them . He called this relationship the Law of Universal Gravitation.
It should! This relationship, known as Coulomb's Law, is very similar to Newton's Law of Universal Gravitation. As you can see, the electrostatic constant, k, is much, much bigger than the universal gravitation constant, G. Differences Between These Forces.
Electric forces, like gravitational forces, are one of the four fundamental forces of the universe, and because of this, they have many similarities.
Similarities between Gravitational fields and Electric fields - 09/10/12 Physics lesson w/ Mr Hampshire
The main difference between Gravitational and Electreic fields is that masses always gravitate towards eachother where charges can attract or repel.
In a uniform Gravitational or Electrical field, all field lines act perpendicular to the surface. All field lines are of equal spacing, signifying a uniform force. In a Gravitational field, the field lines act towards the mass creating the field and show the direction that a test mass would travel.
In a radial field, all field lines point towards the center (origin) of the circular field. Therefore, was the distance (r) from the center increases, the spacing between field lines also increases and this signifies a decrease in attractive force.
Electric field and gravitational field are two concepts bound with the field model. Both of these fields are models that are used to explain the behavior of charges, magnets and masses. These field models are very important in fields such as electrical engineering, electronic engineering, physics, astrophysics, cosmology, ...
Gravitational Field. Gravitational field is produced by any mass in the space. There are very important concepts in gravitational fields such as gravitational field intensity and gravitational potential. The gravitational field intensity is also referred as the gravitational acceleration.
One is required to describe the other. An electric field is said to be produced by all electric charges whether they are moving or stationary. An electric field can also be produced using any time varying magnetic fields. There are several important factors of electric fields. These are electric field intensity, electric field potential, and electric flux density. The electric field intensity is defined as the force on a unit point charge from the electric field. This is given by the formula E = Q/4πεr 2, where Q is the charge, ε is the electric permittivity of the medium and r is the distance of the point from the point Q charge. The electric potential is defined as the amount of work on a unit charge that is required to bring the unit charge from infinity to the given point. The equation for calculating this is V = Q/4πεr where all the symbols have the previous meanings. Another very important aspect of the electric field is the electric flux density. Electric flux density is a measurement of the number of electric field lines going perpendicular to a given unit area surface. Gauss’ law and Ampere’s law are very important when studying these electric fields.
Electric flux density is a measurement of the number of electric field lines going perpendicular to a given unit area surface. Gauss’ law and Ampere’s law are very important when studying these electric fields.
The forces identified by both laws are conservative forces, which means that the work done on any object by these forces is independent of the direction taken by the objects. It is determined by the initial and final position of the object under consideration only.
Coulomb’s law in electrostatics explains how static electric charges interact with each other when they are in each other’s field of influence. This law states that. The force of attraction or repulsion between two stationary electric point charges is directly proportional to the product of the magnitude of two charges and is inversely proportional ...
Since the sign of mass is always positive , the gravitational force is always attractive, while the electric force can be either attractive or repulsive because the sign of electric charge can be either positive or negative. Here it is important to note that, a positive force denotes a repulsive force, while a negative force denotes an attractive ...
