A Dielectric Slab Is Slowly Inserted Between the Plates of a Parallel

question 15

Multiple Choice

A dielectric slab is slowly inserted between the plates of a parallel plate capacitor, while the potential difference between the plates is held constant by a battery. As it is being inserted:

• A) the capacitance, the potential difference between the plates, and the charge on the positive plate all increase
• B) the capacitance, the potential difference between the plates, the charge on the positive plate all decrease
• C) the potential difference between the plates increases, the charge on the positive plate decreases, and the capacitance remains the same
• D) the capacitance and the charge on the positive plate decrease but the potential difference between the plates remains the same
• E) the capacitance and the charge on the plate increase but the potential difference between the plates remains the same
