A parallel plate capacitor is charged and the charging battery is then disconneted. If the plates of the capacitor are moved further apart by means of insulating handles.

A

the charge on the capacitor increases

B

the voltage across the plates increases

C

the capacitance increases

D

the electrostatic energy stored in the capacitor increases

Text Solution

Verified by Experts

The correct Answer is:
B, D
Charging battery is removed .Therefore q= constant
Distance between the plates is increased .Therefore C decreased Now `V=q//c,q` is constant decreasing
Therefore V should increase
`U=1/2q^(2)/c` again q is constant and C is decreasing
Therefore U should increase `therefore` Correct are (B) and (D).
