The plates of a parallel plate capacitor with no dielectric are connected to a voltage source. Now a dielectric of dielectric constant \( \mathrm{K} \) is inserted to fill the whole space between the plates with voltage
\( \mathrm{P} \) source remaining connected to the capacitor.
(A) the energy stored in the capacitor will become \( \mathrm{K} \)-times
W.
(B) the electric field inside the capacitor will decrease to \( \mathrm{K} \)-times
(C) the force of attraction between the plates will increase to \( \mathrm{K}^{2} \)-times
(D) the charge on the capacitor will increase to \( \mathrm{K} \)-times
