A capacitor of capacitance C = 900 pF is charged fully by 100 V battery B as shown in figure (a). Then it is disconnected from the battery and connected to another uncharged capacitor of capacitance C = 900 pF as shown in figure (b). The electrostatic energy stored by the system (b) is:
1
1.5 × 10-6 J
2
4.5 × 10-6 J
3
3.25 × 10-6 J
4
2.25 × 10-6 J
