In an LC oscillator, if values of inductance and capacitance become twice and eight times, respectively, then the resonant frequency of oscillator becomes $x$ times its initial resonant frequency $\omega_0$. The value of $x$ is
Answer: (A) $\dfrac14$
$\omega=\dfrac1{\sqrt{LC}}$; $LC$ becomes $16$ times, so $\omega$ becomes $\dfrac14$ of $\omega_0$.
