2. Electric Potential and Capacitance
medium

After charging a capacitor the battery is removed. Now by placing a dielectric slab between the plates :- 

A

The potential difference between the plates and the energy stored will decrease but the charge on plates will remain same

B

the charge on the plates will decrease and the potential difference between the plates will increase

C

the potential difference between the plates will increase and energy stored will decrease but the charge on the plates will remain same

D

the potential difference, energy stored and the charge will remain unchanged.

Solution

Battery is removed, charge on plate is constant.By placing a dielectric slab between the plates,capacitance increase so the potential difference between the plates and energy stored will decreases.
