A Parallel Plate Capacitor of Capacitance C₀ Has Plates of Area

question 11

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 space between the plates is filled with a material of dielectric constant 3. After the dielectric is added, the magnitudes of the charge on the plates and the potential difference between them are

• A) Q₀, V₀.
• B) Q₀, V₀.
• C) Q₀, V₀.
• D) Q₀, 3V₀.
• E) 3Q₀, 3V₀.
