\\*T = 2\pi\sqrt{LC} \Rightarrow L\; \alpha \frac{1}{C} \\* \frac{L'}{L} = \frac{C}{C'} = \frac{C}{4C} \Rightarrow L' = \frac{L}{4}

 

SHM of LC circuit -

T = 2\pi \sqrt{LC}

L = Coefficent of Self Inductance

C= Capacity of Capacitor

- wherein

L\rightarrow Inductor

C\rightarrow Capacitor

* Formula
