Explanation:
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
