The total polarization charge enclosed by the sphere with r > R is zero as there is an opposite polarity surface polarization charge at r = R with density, σp = ( ε − ε0) q 4πεR2. The total surface charge σp4πR2 = (ε − ε0)q / ε is equal in magnitude but opposite in sign to the polarization point charge at the origin.
