उत्तर
- False
Displacement can become zero when the initial and final positions of the object are the same. - False
Displacement is the shortest measurable distance between the initial and final positions of an object. It cannot be greater than the magnitude of the distance travelled by an object. However, sometimes it may be equal to the distance travelled by the object.
