Question
A parallel plate capacitor of capacitance C0has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0on its plates. The plates are pulled apart to a separation 2d while the capacitor remains connected to the battery. You may neglect edge effects at all times. After the plates are 2d apart, the magnitude of the charge on the plates and the potential difference between them are
A. (1/2)Q0,(1/2)V0
B. Q0,V0
C. 2Q0,2V0
D. Q0,2V0
E. Q0, (1/2)V0
Explanation / Answer
C. 2Q0,2V0
