Two capacitors of capacitance C, have charges Q,－Q and 2Q,－2Q respectively. Their terminals are then connected（higher-higher,lower-lower). Find (a) the final potential difference across each capacitor; (b) the energy difference of the system before and after connection; (c) Where did the “lost” energy go?
