A parallel plate capacitor of capacitance C0 has plates of area A with spacing d between them. When connected to a battery of voltage V0, it has a charge of magnitude Q0 on its plates. Then it is disconnected from the source and the 2d plates are separated without discharging them. After they are 2d separated, the new capacitance and the potential difference between the plates are: a-) 2 Co, 2Vo b-) 1/2 Co, 2 Vo c-) Co, 2Vo d-) 1/2 Co, Vo
