Question

A particle is moving in a circular path of radius r. What would be the displacement after half a cycle? Explain

Answer 1

Answer:

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.

Explanation:

hope you understand mate

Answer 2

Explanation:

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

1.Path '1' is the displacement as its shortest distance between start and end points.hence displacement in this case is 2r.where r is radius. According to your question, the body moves from point A to point B thereby completing half a revolution. Therefore it will be equal to the diameter or r+r=2r.
