Less than natural frequency

Vedclass · Answer

(B) The correct option is $B$. The angular frequency of damped oscillation is given by the formula: $\omega^{\prime} = \sqrt{\omega_0^2 - \left(\frac{b}{2m}\right)^2}$ Since the term $\left(\frac{b}{2m}\right)^2$ is positive,it follows that $\omega^{\prime} Here,$\omega_0 = \sqrt{\frac{k}{m}}$ is the natural angular frequency. Since the frequency $f$ is related to the angular frequency $\omega$ by the relation $\omega = 2\pi f$,the frequency of damped oscillation $f^{\prime}$ will also be less than the natural frequency $f_0$.
