A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 10

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. The plates are pulled apart to a separation 2d while the capacitor remains connected to the battery. After the plates are 2d apart, the magnitude of the charge on the plates and the potential difference between them are

• A) Q₀, V₀
• B) Q₀, V₀
• C) Q₀, V₀
• D) 2Q₀, V₀
• E) 2Q₀, 2V₀
