  • question_answer
    A body executes simple harmonic motion. The potential energy (RE.), the kinetic energy (K.E.) and total energy (T.E.) are measured as a function of displacements. Which of the following statements is true

    A) RE. is maximum when \[x=0\]

    B) K.E. is maximum when \[x=0\]

    C) T.E. is zero when \[x=0\]

    D) K.E. is maximum when x is maximum

    Correct Answer: B

    Solution :

    In S.H.M., at mean position i.e., at \[x=0\] kinetic energy will be maximum and pE will be minimum. Total energy is always constant.
