Epsilon varies as V

A parallel plate capacitor is filled by a dielectric whose relative permittivity varies with the applied voltage $V$ as $\epsilon = \alpha V$ where $\alpha = 2V^{-1}$ . A similar capacitor with no dielectric is charged to $V_0 = 78 V$ . It is then connected to the uncharged capacitor with the dielectric. Find the final voltage on the capacitors.
