Question

a particle is moving in a circle of diameter 2 metre calculate the distance covered and displacement when it completes 5 revolution

Answer 1

Answer:

Distance travelled by the particle in five revolutions is 31.4 m.

Explanation:

Diameter of the circle = 2 m

Radius of the circle = 2 / 2 = 1 m

Distance travelled by the particle (in one revolution) = ‘2πr’ m

= 2*3.14*1 m

= 6.28 m

Distance travelled by the particle in one revolution = 6.28 m

Distance travelled by the particle in five revolutions = 6.28*5 m

= 31.4 m

Hence, the Distance travelled by the particle in five revolutions is 31.4 m.
