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:
`(3/4)` th of a revolution

उत्तर
Distance travelled = (3/ 4) of perimeter of circle.
So distance travelled is = (3π r/ 2).
Displacement can be calculated ass = √r2+r2 = √2r.
