A thin, square, conducting plate 51.5 cm on a side lies in the xy plane. A total charge of 4.25 10-8 C is placed on the plate. You may assume that the charge density is uniform.
(a) Find the charge density on each face of the plate.
(b) Find the electric field just above the plate.
(c) Find the electric field just below the plate.
