D The charge on condenser will reduce to one third 4 A capacitor of capacity C is connected with a battery of potential V in parallel The distance between its plates is reduced to half at once assuming that the charge remains the same Then to charge the capacitance upto the potential V again the energy given by the battery will be A CV4 B CV 4 C 3CV 4 D CV 150
