Question

A particle is a moving in a circle of diameter 20m. What is tha distance and displacement if it's first round is 1 solve with solution

Answer 1

Distance will be it's circumference that will be equal to 2πr=2×3.14×10=62.8
And displacement will be 0 as it came back to its initial position

Answer 2

                                                      hii :)
_____________________________________________________________
Here
        Radius of circle=20/2=10 m
 
The distance that the particle will travel will equal to circuference of the circle

 Circumference of circle = 2*pi*r
                                     2*22*10
                                          7
                                   
                                      440
                                        7
      
                                      62.85 m

The displacement of the body will be zero as the after one revolution the particle will back on its statrting poin
Thus displacement=0
