Question

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

Answer 1

Displacement is the shortest distance between Initial point and final point

therefore the shortest distance will be its diameter , that is 2r your answer

Answer 2

Answer:

Hope it help you

Explanation:

The answer will be 2r.

After the particle covers half path of the circle, the displacement can be easily calculated by measuring the distance between initial and final points. Displacement after half circle = AB=OA + OB Hence, the displacement after half circle is 2r
