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.

Explanation:

We are given that

Length of side,l=6.4 cm=

1 m=100 cm

Total charge,q=

We have to find the magnitude E of the electric field just off the center of the plate.
