Question

A body moving along the circumference of the circle complete 2 revolutions if the radius of the path is R the ratio of displacement to the covered path will be ​

Answer 1

Answer:

Displacement is the minimum distance between the start and end point. Hence, the displacement in this case will be the diameter of the circle, i.e., 2R.

Distance is the length of path covered by the particle/object. Here, the distance will be πR.

Therefore, the ratio of displacement to distance is 2:π

Answer 2

The final position of body after 2 revolutions is same as initial position hence the displacement of the body is zero .

So , the ratio of displacement to the covered path will be ​ zero.
