Applying Gauss’ Law: Planar Symmetry
shows cross-sections through two large parallel nonconducting sheets with identical distribution, of positive charge with surface charge density What IS f at points (a) above the sheets. (b) between them and (c) below them A square metal plate of edge length 8.0 cm and negligible thickness has a total charge of 6.0 X 1O C. (a) Estimate the magnitude E of the electric field just off the center of the plate (at. say. a distance of 0.50 by assuming that the charge is spread uniformly over the two faces of the plate. (b) Estimate E at a distance of 30m (large relative to the plate size) by assuming that the plate is a point charge A large flat nonconducting surface has a uniform charge density A small circular hole of radius R has been cut in the middle.
