A parallel plate 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, En and u are related to the previous ones as
(a) Q > Q0
(b) V > V0
(c) E > E0
(d) u > u0
