Question

A body moving along a circle completes two revolutions what is the ratio of its displacement to covered path

Answer 1

Answer is 0 because he come back in his original position
Displacement - the minimum distance between initial point and final point 

Answer 2

ZERO

As displacement is defined as the minimum distance between initial and final position so after completion of 2 complete revolution , initial and final position become same.

So, displacement = 0
therefore,

 $\frac{Displacement}{distance} = 0$
