- It cannot be zero.
- Its magnitude is greater than the distance travelled by the object.

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.

Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.
Assertion: If the displacement of the body is zero, the distance covered by it may not be zero.
Reason: Displacement is a vector & distance is a scalar quantity.
