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: 
  • a)
    3.25 x 10-6 J
  • b)
    2.25 x 10-6 J
  • c)
    1.5 x 10-6 J
  • d)
    4.5 x 10-6 J
Correct answer is option 'B'. Can you explain this answer?
