A parallel plate capacitor of plate area and plate separation is charged to potential difference and then the battery is disconnected. A slab of dielectric constant is then inserted between the plates of the capacitor so as to fill the space between the plates. If and denote respectively, the magnitude of charge on each plate, the electric field between the plates (after the slab is inserted) and the work done on the system, in question, in the process of inserting the slab, then:

A parallel plate capacitor is charged by a battery.
The battery is disconnected and a dielectric slab is inserted to completely fill the space between the plates. 
How will (i) its capacitance, (ii) electric field between the plates and (iii) energy stored in the capacitor be affected ? Justify your answer giving necessary mathematical expressions for each case.
