force F acts vertically downward on the box. The force exerted by each of the two ropes is denoted by T. A force diagram, showing the four forces that act on the box in equilibrium, is shown in the figure. The magnitude of force F is 410 N. The magnitude of force T is closest to:
The magnitude of the force exerted on each charge is calculated using the following formula: |F|= ∣∣kq1q2r2∣∣= ∣∣∣(9 × 109 N⋅m2/C2)(18 × 10−6 C)(−7 × 10−6 C)(0.21 m)2∣∣∣ = 25.7143 N Imagine that the charges of an electron and a proton in a hydrogen atom are of magnitude 2.2 × 10−19 C but of opposite signs.
An external force F acts vertically downward on the box. The force exerted by each of the two ropes is denoted by T. A force diagram, showing the four forces that act on the box in equilibrium, is
The magnitude of the force on the charge is calculated using the following formula: |Fe|= |qE|=|−6 C×12 N/C|= 72 N A +3.4 × 10−6 C test charge experiences forces from two other nearby charges: a 13-N force due east and an 15-N force due west. What is the direction of the electric field at the location of the test charge? WEST
If the distance between two spherical charged objects decreases by a factor of two, then the electrical force between the objects. increases by a factor of four. A rubber rod is rubbed with fur, so that the fur becomes positive.
If the plates of a charged parallel plate capacitor were moved further apart, while the charge on the plates is kept constant, the potential energy of each of the charges on the capacitor would. increase. A capacitor consisting of two separated parallel horizontal plates has a uniform electric field directed upward.
