A particle is moving in a circle of diameter `5m`. Calculate the distance covered and the displacement when it completes `3 ` revolutions.

Answer» Correct Answer - `15 pi` metre ; zero
Here, diameter , `d = 5 m`
Distance covered in `3` revolutions ` = 3 xx 2 pi r = 3 xx pi d = 15 pi metre`
Displacement ` = 0` , as final position coincides with the initial position.
