Pure R, L and C Circuits

The reactance of a capacitor is $X_C$ . If the frequency and the capacitance are doubled, then the new reactance will be

Show answer and solution

Answer: (c)

$X_C = \frac{1}{2\pi f C} \propto \frac{1}{fC}$
$f \to 2f$ , $C \to 2C$ : $X_C' = \frac{X_C}{2 \times 2} = \frac{X_C}{4}$
So the answer is (c) $\frac{X_C}{4}$ .
