प्रश्न
Under what conditions can a body travel a certain distance and yet its resultant displacement be zero ?

उत्तर
When the body comes back to its starting point, its resultant displacement is zero. It is because it has covered a certain distance in due course of time; however, there is no difference between the initial and final positions.
