Question

Chapter 23, Problem 037 A square metal plate of edge length 7.1 cm and negligible thickness has a total charge of 7.9 x 106 C. (a) Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.62 mm from the center) by assuming that the charge is spread uniformly over the two faces of the plate. (b) Estimate E at a distance of 41 m (large relative to the plate size) by assuming that the plate is a charged particle.
