A Parallel Plate Capacitor of Capacitance C0 Has Plates of Area

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.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:

A) C0, Q0
B) C0, Q0
C) C0, Q0
D) 2C0, Q0
E) 2C0, 2Q0
