9. An air-filled parallel plate capacitor is connected to a battery of voltage \(V_0\). There is charge \(Q_0\) on each plate, energy \(U_0\) stored between the plates and an electric field of \(E_0\) between the plates. The capacitor remains connected to the battery and a dielectric material with a dielectric constant of \(K\) is then placed between the plates of the capacitor. What are the new values of \(V\), \(Q\), \(U\), and \(E\)?      (10)
