    Energy of simple harmonic motion depends on

    A)  \[\frac{1}{{{\omega }^{2}}}\]                                    

    B)  \[\omega \]

    C)  \[\frac{1}{{{a}^{2}}}\]                                   

    D)  \[{{a}^{2}}\]

    Correct Answer: D

    Solution :

                    The total energy of simple hormonic motion is given by E = Kinetic energy + potential energy or      \[E=\frac{1}{2}m{{\omega }^{2}}({{a}^{2}}-{{y}^{2}})+\frac{1}{2}m\,{{\omega }^{2}}{{y}^{2}}\] or      \[E=\frac{1}{2}{{\omega }^{2}}{{a}^{2}}\] Here,  \[E\propto {{a}^{2}}\]
