प्रश्न
A body is moving along a circular path of radius r. What will be the distance and displacement of the body when it completes:
Half a revolution

उत्तर
In this case Distance travelled =half of the parameter of circle.
So distance travelled is =n r. Displacement= diameter of circle
So displacement is 2r.
