Question

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

Answer 1

Hi there !!
Here's your answer

Given ,
Diameter of the particle = 5m
Radius = 5/2 = 2.5m

Distance covered in one revolution = circumference of the circular path
= 2πr or πd
= 3.14 × 5 m
= 15.7m

Distance in 3 revolution = 15.7m × 3

= 47.1m

Since the body is complete 3 " revolutions " , it is crossing the initial and final point 3 time and since the path is circular, the initial and final points coincide with each other .
Thus , the displacement will be zero.

Hope it helps :D

Hey!

_______________

Diameter of circle = 5 m
Radius = 5/2 = 2.5 m

Distance travelled = 2πr
= 2 × 3.14 × 2.5
= 15.7 m

15.7×3 = 47.1 m

Displacement = Shortest distance travelled
= 0

Since starting and ending points are same.
