Electrostatic Potential and Capacitance

A capacitor of capacitance C=900C = 900 pF is charged fully by a 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=900C = 900 pF as shown in figure (b). The electrostatic energy stored by the system (b) is:

Question 42 as printed in the NEET 2022 booklet

  1. A.1.5×10−61.5 \times 10^{-6} J
  2. B.4.5×10−64.5 \times 10^{-6} J
  3. C.3.25×10−63.25 \times 10^{-6} J
  4. D.2.25×10−62.25 \times 10^{-6} J✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
