Parallel Plate Capacitor

The plates of a parallel plate capacitor of capacity ' $C_1$ ' are moved closer together until they ant half their original separation. The new capacitance ' $C_2$ ' is

Show answer and solution

Answer: (c)

$C = \frac{\varepsilon_0 A}{d} \propto \frac{1}{d}$
$d \to \frac{d}{2} \Rightarrow C$ doubles.
So the answer is (c) $C_2 = 2C_1$ .
