A condenser is charged and then battery is removed. A dielectric plate is put between the plates of condenser, then correct statement is

Two condensers of capacity C and 2C are connected in parallel and these are charged upto V volt. If the battery is removed and dielectric medium of constant K is put between the plates of first condenser, then the potential at each condenser is.

After charging a capacitor the battery is removed. Now by placing a dielectric slab between the plates
