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) 3.25 x 10-6 J
(2) 2.25 x 10–6 J
(3) 1.5 x 10–6 J
(4) 4.5 x 10–6 J
