A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 42

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. While it is connected to the battery the space between the plates is filled with a material of dielectric constant 3. After the dielectric is added, 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) 3Q₀, V₀
• E) 3Q₀, 3V₀
