a parrel. plate cap. is charged upto 100v.a 2mm insulator sheet is inserted between the plates.then to maintain same potential difference,distance between the capacitor plate is increased by 1.6mm.so dielectric constant of the capacitor is? the question is solved by making initial and final capacitance equal...i guess charge in second case wont be equal ...plz clear my confusion

charge will remain same as the battery is disconnected so no source of extra charge is there...
