MCQ
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 $\cos \omega \,t((\omega \ne {\omega _0})$ is applied to the oscillator. The time displacement of the oscillator will be proportional to
- A$\frac{m}{{\omega _0^2 - {\omega ^2}}}$
- ✓$\frac{1}{{m(\omega _0^2 - {\omega ^2})}}$
- C$\frac{1}{{m(\omega _1^2 + {\omega ^2})}}$
- D$\frac{m}{{\omega _1^2 + {\omega ^2}}}$
