Question

In order to receive full credit you must show all your work. Be detailed, explain ALL steps, the more you explain the better. This is good practice for exam questions where you will need to be detailed and show all your steps, thoughts, and arguments in order to receive the majority of the points. 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:

Explanation / Answer

Q is constant

sigma = eo*E is also constant

Vo = E*d

now d = 2d

V' = 2Vo

and we know that

C = Q/Vo

C' = Q/V'

C' = Q/2Vo

C' = C/2
