A body is revolving with a constant speed along a circular path. If the direction of its velocity

is reversed, keeping speed unchanged, then

  1. A

    The centripetal force does not suffer any change in both magnitude and direction

  2. B

    The centripetal force does not suffer any change in magnitude but its direction is reversed

  3. C

    The centripetal force disappears

  4. D

    Centripetal force will be doubled

    Solution:

    Even though the direction of velocity is changed, the centripetal force must be towards the centre only angular velocity changes its direction.

     So option ‘A’ is correct because its speed is remains constant whether the velocity direction is

     along clock wise or anti clock wise, centripetal force do not suffer any change in magnitude

     and direction. Remaining options B, C, D are not true
