A solid conducting sphere of radius a is enclosed in a concentric shell of radius `b gt a`. The charge on the inner sphere is `3muC` and on the conducting shell is `-10muC`. The potential difference between the conductors is V. If `+10muC` additional charge is given to the outer shell, the new potential difference is
