Question

a particle is moving in a circle of diameter 6m . calculate the distance covered and the displacement when it competed 4 revolution​

Answer 1

Answer:

Distance = 75.4 m

Displacement = 0

Explanation:

distance of a particle moving in a circular path gonna be equal to the circumference of a circle.

radius = diameter / 2

6/2 = 3m

distance ( in circular path ) = 2πr

=> 2 X 22 / 7 x 3

=> 44 X 3 /  7

=> 18.85 m

now, since the paticle is taking 4 revolution , we gonna multily 4 to the circumference:-

After 4 revolution distance: 4 x 18.85m

: 75.4 m

displacement will be 0 (zero) since the initial and final position will be the same.

I HOPE THIS WILL HELP YOU OUT:)
