Two capacitors having capacitance C 1 and C 2 respectively are connected as shown in figure. Initially, capacitor C 1 is charged to a potential difference V volt by a battery. The battery is then removed and the charged capacitor C 1 is now connected to uncharged capacitor C 2 by closing the switch S. The amount of charge on the capacitor C 2 , after equilibrium, is

1. V ) C C ( C C 2 1 2 1 +
2. V C C ) C C ( 2 1 2 1 +
3. V ) C C ( 2 1 +
4. V ) C – C ( 2 1

Correct answer: V ) C C ( C C 2 1 2 1 +
