Answer:
2r
Explanation:
The displacement is the minimum distance between the initial position and final position.
Suppose a particle starts at a point A at the periphery of the circle and after covering half the circle, particle is at point B.
The minimum distance between points A and B is AB which is also the diameter of the circle.
Therefore, displacement after covering half the circle =Diameter=2r
