Electric Potential at a Point in Space Due to a Point Charge Q

Two condenser...

Question

Two condensers of capacities $2 C$ and C are joined in parallel and charged up to potential V. The battery is removed and the condenser of a capacity C is filled completely with a medium of dielectric constant K. The potential difference across the capacitors will now be

\frac{3 V}{K + 2}
