# Point charge above a conducting plate

A point charge Q lies at a distance D above a large grounded conducting plate.

a) Calculate the surface charge density induced on the plate as a function of the radius r from the foot of the perpendicular drawn from the charge.

b) Show that the total induced charge is -Q.
