Answer:
2r
Explanation:
As we know that
The displacement is the total distance measured between the initial or start and final or destination point
If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point
We attached the diagram for better understanding
As per the diagram.
The displacement after half-circle is
AB = OA + OB
= r + r
= 2r
