A Parallel Plate Capacitor of Capacitance C0 Has Plates of Area

question 7

Multiple Choice

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 magnitude of the charge on the plates and the potential difference between them are:

• A)Q0, V0
• B)Q0, V0
• C)Q0, V0
• D)Q0, 2V0
• E)2Q0, 2V0
