Name: A parallel plate capacitor which has capacitance 5.2pF is fully charged by a battery to a potential difference 14.3V between the plates. The battery is disconnected and a dielectric material (k=119) is inserted between the plates. What is the ratio of new potential energy to the old potential energy of the capacitor?
