A spherical capacitor is made of two conducting sphericalshells of radii a and b = 3a . The space between the shells is filled with a dielectric of dielectric constant K = 3upto a radius c = 2a as shown. If the capacitance of given arrangement is n timesthe capacitance of an isolated of an isolated sphericalconducting shell of radius a. Then find value of n .
