Physics Electrostatics Potential & Capacitance Matching Type Question MCQ (Single Correct)

The area of parallel plates of an air-filled capacitor is and the distance between them is 0.01 m. The potential difference across the plates is 3000 V. When a 0.01 m thick dielectric sheet is introduced between the plates, then the potential difference decreases to 1000 V.

                                      Column I

Column II

A.

Capacitance of air-filled capacitor (in F)

I.

B.

Charge on each plate (in C)

II.
