NCERT Exercise 2.8 - Electrostatic Potential and Capacitance
Question: In a parallel plate capacitor with air between the plates, each plate has an area of 6 × 10⁻³ m² and the distance between the plates is 3 mm. Calculate the capacitance of the capacitor. If this capacitor is connected to a 100 V supply, what is the charge on each plate of the capacitor?
Answer: Capacitance = **18 pF**. Charge on each plate = **1.8 × 10⁻⁹ C**.
