Resonance, Bandwidth & Q Factor

In series LCR resonant circuit, the capacitance is changed from C to 3 C. To obtain the same resonant frequency, the inductance should be changed from $L$ to

Show answer and solution

Answer: (a)

Same resonant frequency needs the same product $LC$ .
$L' \times 3C = LC \Rightarrow L' = \dfrac{L}{3}$
So the answer is (a) $\dfrac{L}{3}$ .
