Question

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 and half revolution. only diagram ,no solution.please fast​

Answer 1

A body is moving along a circular path of radius r. ... Since distance is the length of path covered therefore it will be equal to half the circumference i.e. 1/2 × 2pi r or pi × r. And the displacement is equal to the distance between initial and final point. Therefore it will be equal to the diameter or r+r=2r.
