L, C and R represent the physical quantities, inductance, capacitance and resistance respectively. The combination(s) which have the dimensions of frequency areA. `L/C`B. `(LC)^(2)`C. `(LC)^(-1//2)`D. `((LC)/(R))^(1//2)` |

Answer» Correct Answer - C The resonant frequency, `f=(1)/(2pisqrt(LC)) = 1/(2pi(LC)^(1//2))` `:. F = 1/(2pi)(LC)^(-1//2)` `:. (LC)^(-1//2)` will have the dimensions of frequency as `1/(2pi)` is dimensionless. |
