Question:

A parallel-plate capacitor has plates with an area of 405 cm2 and an air-filled gap between the plates that is 2.25 mm thick. The capacitor is charged by a battery to 575 V and then is disconnected from the battery.

(a) How much energy is stored in the capacitor?

(b) The separation between the plates is now increased to 4.50 mm. How much energy is stored in the capacitor now?
