Question

A particle is moving in a circle of diameter 5m. calculate the distance covered and displacement when it covers one and half revolution
Give Answer In Full Step Or Method.

Answer 1

Heyy Bro !
____________________________________________________________
Suppose a circle with diameter 5 m 
then its radius will be 5/2 m 
first lets calculate distance :
the total distance in one and half revolution is 2 π r + π r 
                                                                     =  3π r
                                                                     =  3  X 22/7 X 5/2
                                                                     =  23.57 m
____________________________________________________________
Displacement :
When  it cover one revolution the displacement becomes zero 
so the total displacement is half revolution 
and if we take shortest distance it will be its diameter  
So. Displacement becomes 5 m

Answer 2

Explanation:

A particle is moving in a circle of 5m diameter. What is its displacement when it completes one and a half revolution?

When the particle completes 1 revolution, then the displacement is zero. Now, in the next half revolution, the displacement is equal to the diameter of the circle. so total displacement of the particle is Displacement = 5 m

or

a circle with diameter 5 m

then its radius will be 5/2 m

first lets calculate distance :

the total distance in one and half revolution is 2 π r + π r

= 3π r

= 3 X 22/7 X 5/2

= 23.57 m

for displacement it cover one revolution the displacement becomes zero

and because of so the total displacement is half revolution

and if we take shortest distance it will be its diameter

So now Displacement becomes 5 m…..

do our answer is 5m

hope you understand
