  • question_answer
    A charged particle enters in a magnetic field in a direction perpendicular to the magnetic field. Which of the following graphs show the correct variation of kinetic energy of the particle with time t?

    A)

    B)

    C)

    D)

    Correct Answer: D

    Solution :

    [d] The change in K.E. is equal to work done by net force which is zero because the magnetic force is perpendicular to velocity. K.E. remains constant.
