Question

3. The area of a parallel plate of an air capacitor is 0.2m² and the distance between them is 0.01m. The potential difference between its plate is 3000V. When a 0.01m thick sheet of an insulator is placed between the plates, the potential difference decreases to to 1000V. Determine I. Capacitance of the capacitor before placing the sheet. II. charge on each plate. III Dielectric constant of the material, IV. Capacitance after placing the dielectric V. Permittivity of the dielectric​
