A parallel plate capacitor is charged and then isolated. The effect of increasing the plate separation on charge, potential and capacitance respectively are

A

Increases, decreases, decreases

B

Constant, increases, decreases

C

Constant, decreases, decreases

D

Constant, decreases, increases

Text Solution

Verified by Experts

The correct Answer is:
B

After separation charge = constant
Capacity C `=(epsilon_0A)/d implies C darr implies d uarr`
`V =Q/C implies V uarr implies C darr`
