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. | |
C. | Dielectric constant of the material | III. | 3 |
D. | Capacitance after the dielectric sheet is introduced | IV. |
Choose the correct answer from the option given below.
