Compute all parts of given question:

Question: A parallel plate capacitor with plates of area 500 cm2 is charged to a potential difference V and is then disconnected from the voltage source. When the plates are moved 0.4 cm further apart, the voltage between the plates increases by 100V.

Part A: What is the charge Q on the positive plate of the capacitor?

Part B: How much does the energy of the capacitor change due to the movement of the plates?

Having trouble with this physics question, can you please explain with the answer.
