How much energy is stored in the capacitor

Reference no: EM13239917

A parallel plate capacitor has a charge of 2.66X 10^-11 C after being charged by a 15 V battery. The plates are seperated by 2.0 mm of air. How much energy is stored in the capacitor? if the plate seperation is changed to 12 mm while the charges on the plate remains constant how does the energy change?
