Question

A particle is moving in a circle of diameter 5m. calculate the distance covered and displacement when it covers three revolution.
Give Answer In Full Step Or Method.

Answer 1

Sup' homie!

diameter=5m
radius=5/2m
distance covered = 2πr=2×22/7×5/2=110/7m
displacement=0 because initial and final position are the same.

Hope it helps!

Answer 2

Hello Mate!

If diameter of circle = 5m
Radius = 5m/2

Now, distance or circumference = 2 × 22/7 × r
= 2 × 22/7 × 5 / 2 m
= 110 m / 7 = 15.7 m

Now, distance travelled in 3 revolutions is 3 × 15.7 = 47.1 m

Here, displacement will be zero or " 0 " because a body when starts journey from point A and finished on point A then its displacement is zero.

Hope it helps☺!✌
