    Answer:

    Work done is 0.

    Explanation:

    Given that,

    The circumference of an orbit for a toy on a string is 18 m, r = 18 m

    Centripetal force, F = 12 N

    In the circular path, the centripetal force is always perpendicular to the motion of the object. Thus it makes an angle of 90 degrees with the force and displacement. Hence, we can say that the centripetal force does not do any work on the toy when it follows its orbit for one cycle.
