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.

For changing the capacitance of a given parallel plate capacitor, a dielectric material of dielectric constant $K$ is used, which has the same area as the plates of the capacitor. The thickness of the dielectric slab is $\frac{3}{4} d$, where $'d'$ is the separation between the plates of parallel plate capacitor. The new capacitance $(C')$ in terms of original capacitance $\left( C _{0}\right)$ is given by the following relation
