Assertion (A): If the distance between the plates is increased for a disconnected capacitor, its potential energy decreases.
Reason (R): Energy , is inversely proportional to distance between the plates.

Options

A. Both (A) and (R) are true and (R) is the correct explanation of (A).
B. Both (A) and (R) are true but (R) is not the correct explanation of (A).
C. (A) is true but (R) is false.
D. (A) is false and (R) is also false.

Answer

D

Explanation

(A) is false and (R) is also false.
Explanation: For disconnected capacitor
Q = constant,
Energy =`(Q^(2)d)/(2 epis_(0)A)`
`E prop d`.
