Question

a body moves in a circle of radius r .what is the distance covered and displacement of a body after 2 rounds​

Answer 1

Answer:

distance is = 2×(2πr)

and displacement is zero

Answer 2

Explanation:

Thus, the circumference of the circle of radius 2R would be equal to 2π2R ⇒ 4πR. So, the total distance would be equal to 2 x 4πR ⇒ 8πR. In contrast, the displacement refers to the vector quantity which is equal to the shortest distance between the initial and final position of the object.
