Question

A capacitor that has 10 cm diameter plates, 0.1mm apart, is charged at 100 V and the battery
removed afterwards. What are the charges on each of the platesimmediately after charging the
capacitor? What is the voltage if the distance between plates is increased to 0.5 mm? How
much did the energy stored in the capacitor change when plates are pulled apart?
