The distance between the two plates of a parallel plate capacitor is doubled and the area of each plate is halved. If $C$ is its initial capacitance, its final capacitance is equal to:NEET 2022 (Phase 2)

Options:

Answer:

Solution:

The capacitance of parallel plate capacitor, $C = \frac{ε _{0} A}{d}$ (where, the symbols have their usual meanings.) Given, $d^{'} = 2 d & A^{'} = \frac{A}{2}$ Then, $C^{'} = \frac{ε _{0} ( \frac{A}{2} )}{2 d} = \frac{ε _{0} A}{4 d} = \frac{C}{4}$
