A parallel plate capacitor of capacitance C0 has plateof area A with separation d between them. When it isconnected to a battery of voltage V0 it has chargeof magnitude Q0 on its plates. It is thendisconnected from the battery and the plates are pulled apartto a separation 2d without discharging them. Afterthe plates are 2d apart, What is the magnitude of the charge on the plates and the potential difference between them?
