Resonance, Bandwidth & Q Factor

In an LC circuit, angular frequency at resonance is $\omega$ . The new angular frequency when inductance is made four times and capacitance is made eight times is

Show answer and solution

Answer: (b)

$\omega \propto \dfrac{1}{\sqrt{LC}}$
$L'C' = 4L \times 8C = 32LC$
$\omega' = \dfrac{\omega}{\sqrt{32}} = \dfrac{\omega}{4\sqrt{2}}$ . So the answer is (b).
