Question

Q3. A boy is moving along a circular track of radius R. what is the distance and the displacement of
the boy when he completes half a revolution.​

Answer 1

Explanation:

distance and displacement will be equal in a circular track

Answer 2

Answer:

Displacement is double of radius and the distance we can find out with using formula 2×22 by 7 radius by time and after that divided by 2

Explanation:

The displacement is shortest path covered by an object so if we into the radius by 2 so that is the displacement. And if we have to find the distance using formula of circular motion then we get the answer of the whole circular path after that we have divided by 2 to find half circular path
