A parallel plate capacitor with capacitance C0 is connected to a battery with voltage V0 and is charged fully to a charge Q0. There is an electric field E0 between the plates and energy U0 stored in the capacitor. With the battery still connected, the area of the plates are doubles and the plates are pulled to a distance three times its original distance (while still being small compared to the size of the plates). Find (in terms of the...

A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0
A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0 on its plates. It is then disconnected from the battery and the plates are pulled apart to a separation 2d without discharging them. After the plates are 2d apart, the new capacitance and the potential difference between the plates are (Show your work or reasoning)
