Compute all parts of given question:

Question: A parallel-plate vacuum capacitor has 6.88J of energy stored in it. The separation between the plates is 3.70mm . If the separation is decreased to 1.25mm,

Part I: What is the energy now stored if the capacitor was disconnected from the potential source before the separation of the plates was changed?

Part II: What is the energy now stored if the capacitor remained connected to the potential source while the separation of the plates was changed?

I've been having quite a bit of trouble understanding this question, Thank you so much for your help. Thanks.
