Question table -1

1. An object has moved through a distance. Can it have zero displacement? If yes, support your answer with an example.

Answer- Yes, an object which has moved through a distance can have zero displacement if it comes back to its initial position. Example-if a man walk through a circular path and if it reachs starting point after some time then man’s displacement will be equal to zero.

2. A farmer moves along the boundary of a square field of side 10m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position?

Answer –

3. Which of the following is true for displacement? (a) It cannot be zero. (b) Its magnitude is greater than the distance travelled by the object.

Answer – Neither of the statements is true.

(a) Given statement is false because the displacement of an object which travels a certain distance and comes back to its initial position is zero.

(b) Given statement is false because the displacement of an object can be equal to, but never greater than the distance travelled.
