A parallel plate capacitor is connected to a battery. The quantities charge, voltage, electric field and energy associated with the capacitor are given by \( \mathrm{Q}_{0}, \mathrm{~V}_{0}, \mathrm{E}_{0} \) and \( \mathrm{U}_{0} \) respectively. A dielectric slab is
\( P \) introduced between plates of capacitor but battery is still in connection. The corresponding quantities now given by \( \mathrm{Q}, \mathrm{V}, \mathrm{E} \) and \( \mathrm{U} \) related to previous ones are
W
(A) \( QQ_{0} \)
(B) \( \mathrm{V}\mathrm{V}_{0} \)
(C) \( \mathrm{E}\mathrm{E}_{0} \)
(D) \( \mathrm{U}\mathrm{U}_{0} \)
