A conducting sphere of radius R1 is given a free charge Q. Thesphere is surrounded by an uncharged concentric sphericaldielectric shell having an inner radius R1, an outer radius R2, anda dielectric constant k, The system is far removed from otherobjects.
(a) Find the electric field everywhere in space
(b) What is the potential of the conducting sphere relative toV=0 at infinity?
(c) Find the total electrostatic potential energy of thesystem.
