Question:

A square conducting slab with 5-m sides carries a net charge of 80 μC.

(a) Find the charge density on each face of the slab and the electric field just outside one face of the slab.

(b) The slab is placed to the right of an infinite charged nonconducting plane with charge density 2.0 μC/m2 so that the faces of the slab are parallel to the plane. Find the electric field on each side of the slab far from its edges and the charge density on each face.
