Physics - SHM Question with Solution | TestHub

A particle of mass $m$ is attached to a spring (of spring constant $k$ ) and has a natural angular frequency ${\omega }_0$. An external force $F(t)$ proportional to $\cos \omega t\left(\omega \ne {\omega }_0\right)$ is applied to the oscillator. The time displacement of the oscillator will be proportional to
