Problem

A parallel plate capacitor of capacitance

C

is connected to a battery and is charged to a potential difference

V

. Another capacitor of capacitance

2C

is similarly charged to a potential difference

2V

. The charging battery is now disconnected and the capacitors are connected in parallel to each other in such a way that the positive terminal of one is connected to the negative terminal of the other. The final energy of the configuration is a. zero b.
