Two hollow concentric non-conducting spheres of radius the a and b (a gt b) contain charges Q_(a) and Q_(b) respectively. Prove that potential difference between the two spheres is independent of charge on outer sphere. If outer sphere is given an extra charge, is there any change in potential difference ?
