JEE Main & Advanced Physics Simple Harmonic Motion Question Bank Energy of Simple Harmonic Motion

  • question_answer
     A particle executes simple harmonic motion along a straight line with an amplitude A. The potential energy is maximum when the displacement is                                         [CPMT 1982]

    A)            \[\pm A\]                              

    B)            Zero

    C)            \[\pm \frac{A}{2}\]           

    D)            \[\pm \frac{A}{\sqrt{2}}\]

    Correct Answer: A

    Solution :

               P.E.\[=\frac{1}{2}m{{\omega }^{2}}{{x}^{2}}\] It is clear P.E. will be maximum when x will be maximum i.e., at \[x=\pm A\]
