Question

Two parallel plate capacitors of capacitance C a n d 2 C are connected in parallel and charged to a potential difference V 0 . The battery is then disconnected and the region between the plates of the capacitor C is completely filled with a material of dielectric constant 2 . The potential difference across the capacitors now becomes

Initial state As both capacitors have the same capacitance total charge = C V 0 + 2 C V 0 = 3 C V 0 It will be divided equaly so q 1 = q 2 = 3 C V 0 2 & potential = q C = ( 3 C V 0 2 ) 2 C = 3 V 0 4
