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

    A) \[144\,{{\pi }^{2}}\]    

    B)        \[188\,{{\pi }^{2}}\]

    C) \[288\,{{\pi }^{2}}\]    

    D)        None of these

    Correct Answer: C

    Solution :

    [c] Max. force = mass \[\times \] max. acceleration \[=m4\,{{\pi }^{2}}\,{{v}^{2}}a=1\times 4\times {{\pi }^{2}}\times {{(60)}^{2}}\times 0.02\] \[=288\,{{\pi }^{2}}\]
