Question

A girl running around a circular tract completed one round is said to have done zero displacement......

GIVE REASON.......FOR THE ANSWER

Answer 1

Displacement is the shortest distance travelled from initial to final point by an object . it is find by subtracting the point from where it was started from the point where it reached .

So ,when a person ends from where it started then the displacement is zero .

Answer 2

A girl running around a circular tract completed one round is said to have done zero displacement......

A girl running around a circular tract completed one round is said to have done zero displacement zero.

• Displacement

1. It is termed to be the shortest distance between the initial and final point of a motion.
2. In a circular track, after completing one rotation the girl is at her initial point.
3. Therfore the distance between initial and final point of motion is zero.
4. Hence Displacement is zero

hope it helps
