Two parallel plate capacitors of capacity C and 3C are connected in parallel combination and charged to a potential difference $\displaystyle 18$ V . The battery is then disconnected and the space between the plates of the capacitor of capacity C is completely filled with a material of dielectric constant $\displaystyle 9$ . The final potential difference across the combination of capacitors will be \_\_\_\_ V.
