A parallel-plate capacitor with plates of area 441 cm2 is charged to a potential difference V and is then disconnected from the voltage source. When the plates are moved 5.02 mm farther apart, the voltage between the plates increases by 81.0 Volts. What is the charge on the positive plate of the capacitor? How much does the energy stored in the capacitor increase due to the movement of the plates?
