A parallel-plate vacuum capacitor has 8.38 J of energy stored in it. The separation between the plates

Question:

A parallel-plate vacuum capacitor has 8.38 J of energy stored in it. The separation between the plates is 2.30 mm. If the separation is decreased to 1.15 mm, what is the energy stored

(a) If the capacitor is disconnected from the potential source so the charge on the plates remains constant,

(b) If the capacitor remains connected to the potential source so the potential difference between the plates remains constant?
