Answer & explanation
Correct answer: option 2
Capacitance $ C=\frac{\epsilon_0 A}{d}$
New Capacitance $C' = \frac{\epsilon_0 A}{d/2} = \frac{2\epsilon_0 A}{d} = 2C$
Correct answer: option 2
Capacitance $ C=\frac{\epsilon_0 A}{d}$
New Capacitance $C' = \frac{\epsilon_0 A}{d/2} = \frac{2\epsilon_0 A}{d} = 2C$
