A dielectric slab is introduced between the plates of a capacitor. Then the potential difference and the capacity respectively

By inserting a plate of dielectric material between the plates of a parallel plate capacitor at constant potential, the energy is increased five times. The dielectric constant of the material is

Two identical parallel plate capacitors are connected in series to a battery of 100V . A dielectric slab of dielectric constant 4.0 is inserted between the plates of second capacitor. The potential difference across the capacitors will now be respectively
