A 20-pF capacitor is charged to 3.0 kV and then removed from the battery and connected to

Question:

A 20-pF capacitor is charged to 3.0 kV and then removed from the battery and connected to an uncharged 50-pF capacitor.

(a) What is the new charge on each capacitor?

(b) Find the initial energy stored in the 20-pF capacitor and the final energy stored in the two capacitors. Is electrostatic potential energy gained or lost when the two capacitors are connected?
