Problem
A parallel plate capacitor having capacitance 12 pF is charged by a battery to a potential difference of 10 V between its plates. The charging battery is now disconnected and a porcelain slab of dielectric constant 6.5 is slipped between the plates. The work done by the capacitor on the slab is:
(1) 692 pJ
(2) 508 pJ
(3) 560 pJ
(4) 600 pJ
