प्रश्न
A body moves along a circular path of radius r. When it completes three complete rounds, what is the ratio of distance covered to its displacement?

उत्तर
As after completing 3 revolution in circular motion the displacement is = 0.
so the ratio of distance covered to the displacement is infinite.
