A parallel plate capacitor is charged by a battery, which is then disconnected. A dielectric slab having dielectric constant (relative permittivity) $K$, is now introduced between its two plates in order to occupy the space completely. State, in terms of $K$, its effect on the following:
(i)[1.0]
The capacitance of the capacitor.
(ii)[1.0]
The potential difference between its plates.
(iii)[1.0]
The energy stored in the capacitor.
