In series RLC resonator, if the self inductance and capacitance become double, the new resonant frequency $\displaystyle \left(f_2\right)$ and new quality factor $\displaystyle \left(\mathrm{Q}_2\right)$ will be :
( $\displaystyle f_1=$ original resonant frequency, $\displaystyle \mathrm{Q}_1=$ original quality factor)
Official answer
(1)
$\displaystyle f_2=\frac{f_1}{2} \text { and } \mathrm{Q}_2=\mathrm{Q}_1$
