A parallel plate air capacitor is connected to a battery. The quantities charge, voltage, electric field and energy associated with this capacitor are given by Q0 ,V0 ,E0 and U0 respectively. A dielectric slab is now introduced to fill the space between the plates with the battery still in connection. The corresponding quantities now given by Q,V,Eand Uare related to the previous one as
(A) Q > Q0
(B) V > V0
(C) E > E0
(D) U > U0
