Question

A particle is moving in a circular path of radius r what will displacemet after half a circle
​

Answer 1

Answer: Given, after half the circle, the particle will reach the diametrically opposite point i.e., from point A to point 6. ... Hence, the displacement after half circle is 2r.

Explanation:

 

Answer 2

Answer:

2r

Explanation:

Given, after half the circle, the particle will reach the diametrically opposite point As we know displacement is shortest path between initial and final point. Hence, the displacement after half circle is 2r
