Question

A particle is moving in a circular path of radius 'r' the displacement after half a circle would be-

Zero

πr

2r

2πr​

Answer 1

Answer:

2r

The displacement after half a circle would be. Hence, the displacement aftar half circle is 2r.

Answer 2

Answer:

(c) Given, after half the circle, the particle will reach the diametrically opposite point i.e., from point A to point 6. And we know displacement is shortest path between initial and final point. Hence, the displacement after half circle is 2r.
