Problem
A charge q is placed at the centre of an uncharged hollow metallic sphere of radius a.
(a) Find the surface charge density on the inner surface and on the outer surface.
(b) If a charge q is put on the sphere, what are the surface charge densities on the inner and outer surfaces?
(c) Find the electric field inside the sphere at a distance x from the centre in situations (a) and (b).
