Question

3. An object is moving along a circular path of radius
R. What will be the distance covered and the
displacement of the object after one revolution?​

Answer 1

Answer:

After half revolution the displacement is the length of the diameter which is equal to 2r. Hence the displacement is 2r.

Answer 2

Explanation:

Distance covered by object in one revolution is equal to circumference of the circle .i. e. 2πR. As object comes to his original position after one round, displacement is Zero.
