A parallel plate capacitor of capacitance $C_0$ has plates of area A with separation $d$ between them. When it is connected to a battery of voltage $V_0,$ it has charge of magnitude $Q_0$ on its plates. The plates are pulled apart to a separation $2d$ while the capacitor remains connected to the battery. After the plates are $2d$ apart, the capacitance of the capacitor and the magnitude of the charge on the plates are
