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 ?
