If the plates of a parallel plate capacitor connected to a battery are moved close to each other, then
A. the charge stored in it, increases.
B. the energy stored in it, decreases.
C. its capacitance increases.
D. the ratio of charge to its potential remains the same.
E. the product of charge and voltage increases.
Choose the most appropriate answer from the options given below:

Asked in NEET 2024 · Battery connected or removed

Answer: (4) A, C and E only

Step-by-step solution

The battery stays connected, so V is fixed.

C=(ε₀A)/d rises as d falls: C is true.

Q=CV rises: A is true.

U=1/2CV² rises: B is false.

Q/V=C changes: D is false.

QV=CV² rises: E is true.

So A, C and E only.

Why the other options are wrong
