A parallel-plate capacitor with plates of area 590 cm2 and isconnected across the terminals of a battery. After some time haspassed, the capacitor is disconnected from the battery. When theplates are then moved 0.48 cm farther apart, the charge on eachplate remains constant but the potential difference between theplates increases by 100 V.
(a) What is the magnitude of the charge on each plate?
(b) Do you expect the energy stored in the capacitor toincrease, decrease, or remain constant as the plates are moved thisway? Explain your answer.
(c) Support your answer to Part (b) by determining the change instored energy in the capacitor due to the movement of theplates.
