Question

21. A body is moving along the circumference of a circle of radius 'R' and completes
half of the revolution. Then, the ratio of its displacement to distance is
3
1) 1:2
2) 2:1
3) 2:1
4) 1:2​

Answer 1

Your options are wrong brother. One of the options should be 2:π. The option 2:1 has been given twice.

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

Answer 2

Answer:

2:1 is the answer of your question
