Figure 23 − 50 shows a very large nonconducting sheet that has a uniform surface charge density of σ = − 2.00 μ C / m 2 ; it also shows a particle of charge Q = 6.00 μ C, at distance d from the sheet. Both are fixed in place.
A. x = 0.691 m on the positive axis, and B. x = − 0.691 m on the negative axis. C. In this part, the fields cancel only at the point x ≈ + 0.691 m
problem 23.40. So we have a sheet of charge. That's some distance D to the left of a point charge. Q. At the origin we'd like to do is find out, uh, one of the positive and negative X values where the electric field will be.
