Question

1. A man is moving in a circular path of radius 20 m The displacement after one and a half a circle would be:

Answer 1

Answer:

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.

Displacement after half circle = AB=OA + OB [v Given, OA and 06 = r]

Hence, the displacement after half circle is 2r.

Answer 2

the displacement after half circle is 2r.
