    A particle of mass 1 kg is moving in SHM with an amplitude 0.02 m and a frequency of 60 Hz. The maximum force in newton acting on the particle is                 

    A)  188\[\pi \]2                       

    B)  144\[\pi \]2

    C)  288 \[\pi \]2                      

    D)  12\[{{\pi }^{2}}\]

    E)  None of these

    Correct Answer: C

    Solution :

                    Maximum force \[=m{{\omega }^{2}}a\] \[=m\times 4\pi {{\nu }^{2}}a\] \[=1\times 4{{\pi }^{2}}\times {{(60)}^{2}}\times 0.02\] \[=288\,{{\pi }^{2}}\]
