    A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that:

    A)  its velocity is constant

    B)  its kinetic energy is constant

    C)  it moves in a circular path

    D)  both [b] and [c] are correct

    Correct Answer: D

    Solution :

    A force of constant magnitude, which is always perpendicular to the velocity of the particle does no do work. Hence, KE of the particle is constant. A force is perpendicular to the velocity the particle moves in a circular path. Hence, the correction option is [d].
