An isolated metal sphere of radius R, carrying an electric charge Q, is situated in the medium of relative permitivity, E^r. A test charge is placed at a point p, distance r from the surface of the sphere. Let E^o represent the permitivity of free space. The electric potential at p is given by the expression
