Assignment:
A 100-µF parallel-plate capacitor is charged to 500 V. It is then disconnected from the charging source and insulated.
(a) How much energy is stored on the capacitor?
(b) If the plates are pulled apart to a separation that is twice their initial separation, what energy is stored on the capacitor?
(c) If the answers are not identical, account for their difference.
Provide complete and step by step solution for the question, use formulaes.
