A.

zero

B.

40π cm

C.

20π cm

D.

None of these

Correct option is A

Given:
The body moves in circular path of radius 10 cm. it completes two revolutions along the circular path.
Solution:
For a body in circular motion, the displacement of the object is equal to the length of the shortest path between the final and the initial points.
If the body comes back to its original position, then the displacement of the body is zero.
In this case, the body completes two revolutions along the circular path.
Therefore, it returns to its initial position after completing one revolution.
Hence, the displacement of the body is zero.
