Question

A particle is moving in a circle of diameter 10m. calculate the distance covered and displacement when it covers two revolution.Give Answer In Full Step Or Method.

Answer 1

total distance =
$2 \times 2\pi \: r$
$4 \times 3.14 \times 5$
=62.8
now total displacement =0 because after
completing two revolutions particle come at original place from where it was started.
