Q. $L,\ C$ and $R$ represent physical quantities inductance capacitance and resistance respectively. The combination representing dimension of frequency is
A) LC
B) $(LC)^{- 1/2}$
C) $\left( \frac{L}{C} \right)^{- 1/2}$
D) $\frac{C}{L}$
Explanation
(b) Frequency $= \frac{1}{2\pi\sqrt{LC}}$
So the combination which represents dimension of frequency is $\frac{1}{\sqrt{LC}} = (LC)^{- 1/2}$
