Question

A particle is moving in a circular path of radius r .the displacement after half a circle would be?​

Answer 1

Answer:

When particle moves along half circle, it covers half the circumference therefore distance covered is (2×pi×r)/2 = pi× r. Where r is radius of circle. When particle covers half the circle, it is diametrically opposite to the starting point of its motion. Therefore shortest distance is equal to diameter of circle or 2× r is a displacement

OR

(2×pi×r)/2 = pi× r.

hope it helps plz mark as brainlist

Answer 2

Answer:

2r

Explanation:

displacement is a measure of shortest path between two points where distance is measure of actual path

when it covers half of a circle it means that it's displacement is 2r
