Equivalent capacitance between A and B is

The effective capacitance between points A and B is

Two parallel plate capacitors of capacitances C and 2C are connected in parallel and charged to a potential difference V₀ . 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
