Question

uestions
1. An object has moved through a
distance. Can it have zero
displacement? If yes, support
your answer with an example,
2. A farmer moves along the
boundary of a square field of side
10 m 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?
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 1

Answer:

1.If yes, support your answer with an example. Answer: Yes, zero displacement is possible if an object has moved through a distance. Suppose a ball starts moving from point A and it returns back at same point A, then the distance will be equal to 20 meters while displacement will be zero.

2.A farmer moves along the boundary of a square field of side 10 m 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? Farmer takes 40 s to move along the boundary. Thus, after 3.5 round farmer will at point C of the field.

3.Displacement can be zero. The body may be at rest, therefore, distance travelled is equal to 0. If the final position coincides with the initial position after some time then displacement is zero but distance travelled will not be zero.

Answer 2

$\huge\mathcal\color{teal}{Answer :- }$

Yes, an object moving a certain distance can have zero total displacement. Displacement refers to the shortest distance between the initial and the final positions of the object. Even if an object moves through a considerable distance, if it eventually comes back to its initial position, the corresponding displacement of the object would be zero.
