Question

A body is moving along a circle of radius r. What are the values of distance and displacement in half of the revolutions

Answer 1

Answer:distance will be pieR

And displacement is 2R

Explanation:since displacement is the shortest path b/w two points so in this case diameter will be the shotest path so 2R

And distance is the path taken to reach the points ,in this case semicircular path is taken so pieR
