A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 31

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. 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

• A) C₀, V₀
• B) C₀, V₀
• C) C₀, 2V₀
• D) C₀, 2V₀
• E) 2C₀, 2V₀
