5. A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them.When it is connected to abattery of voltage V0 , it has charge of magnitude Q0 on its plates. While it is connected to thebattery, the space between the plates is filled with a material of dielectric constant 3. After the  dielectric is added, the magnitude of the charge on the plates and the potential difference betweenthem are
