A square metal plate of edge length 6.4 cm and negligible thickness has a total charge of 6.6 x 10-6 C. Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.71 mm from the center) by assuming that the charge is spread uniformly over the two faces of the plate. Express your answer in terms of N/C.
