(b) becomes zero
(c) increases
(d) decreases

Answer:
Correct Answer: 37. (c)
Solution:
- (c) If we increase the distance between the plates its capacity decreases resulting in higher potential as we know $Q=C V$. Since $Q$ is constant (battery has been disconnected), on decreasing $C$, $V$ will increase.
