Suppose there exists a spherical shell (inner radius a and outer radius b) composed of a linear dielectric material. There is a point charge Q located at the center of the spherical shell. The polarization of the shell is given by P = coXmQF € Απεν2 where e is the permitivity of the linear dielectric material.
(a) Determine the volume bound charge density, PB- (b) Determine the surface bound charge density, OB-
