Question

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

Answer 1

➫Answer

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

hope this helps u
