Question

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



plz guys with explaination ​

Answer 1

Answer :-

The distance covered is 47.16m & The displacement is 0 .

The Perfect Explaination:-

Diameter = 5m

Radius = 2.5m

Distance in 1 revolution = Circumference of circle

=>Distance in 1 revolution= 2πr

$= > 2 \times \frac{22}{7} \times 2.5$

=> 15.72

=> Distance in 3 revolution = 3× 15.71

=> Distance in 3 revolution is 47.16 m.

Here, the body comes back to the same position the displacement is 0.

=>Distance in 1 revolution= 2πr

$= > 2 \times \frac{22}{7} \times 2.5$

=> 15.72

=> Distance in 3 revolution = 3× 15.71

=> Distance in 3 revolution is 47.16 m.

Here, the body comes back to the same position the displacement is 0.
