PhysicsElectrostatic Potential and CapacitanceMHT CET 2022

Two parallel air capacitors have their plate area 100cm and 500cm, respectively. They have the same charge and potential. If the distance between the plates of the first capacitor is 0.5 mm, the distance between the plates of he second capacitor is

Answer: (C)

Solution

Same charge and same potential means the two capacitors have the same capacitance . For an air capacitor , so . Therefore $ =
