A Parallel Plate Capacitor of Capacitance C0 Has Plates of Area

question 54

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 capacitance and the potential difference between the plates are

• A) C0, V0.
• B)C0, V0.
• C)C0, V0.
• D)3C0, V0.
• E)3C0, 3V0.
