Question

A particle is moving in a circular path of diameter 10 meter . Find disrance and displacement of the body on completing 2 revolutions.

Answer 1

Hi there !
Answer down here ⬇️⬇️

Given,
Diameter of the circular path = 10m

Distance in one revolution = circumference of the circular path
=πd
= 3.14 × 10
= 31.4 m

Distance covered in 2 revolution = 31.4×2m = 62.8 m

Thus,
The distance covered in 2 revolution is 62.8 m

The DISPLACEMENT :
Since the body is moving in a circular path , the initial and the final points will lie on the same point ie, they'll coincide with each other. So,
The DISPLACEMENT will be 0

Hope it helps :D

Answer 2

Hey!

______________

Diameter of circular path = 10 m
Radius = 10/2 = 5 m
Circumference of circular path = 2πr
= 2 × 22/7 × 5
= 31.4 m

Distance travelled = 31.4 × 2 = 62.8 m

Displacement = Shortest distance travelled
Displacement = 0
As starting point and ending point is same.
