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:
Two full revolutions

उत्तर
Distance travelled is two times the perimeter of cirle.
So distance travelled is =4π r.
Displacement =0 as starting and ending point are coinciding.
