(8c23p35) A square metal plate of edge length 9.0 cm and negligible thickness has a total charge of 8.50x10-6 C. Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.50 mm) by assuming that the charge is spread uniformly over the two faces of the plate. 1.04E-3N/C Submit Answer Incorrect. Tries 1/4 Previous Tries Estimate E at a distance of 40 m (large relative to the plate size) by assuming that the plate is a point charge. Submit Answer Tries 0/4 This discussion is closed.
