questions
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 thefarmer at the end of 2 minutes 20seconds 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:

Explanation:

1) The object moved through a distance can have zero displacement if it returns back to its original position for example motion of a particle on circular track or a round trip

2) time taken to complete one round is 40 secs

2 min 20 secs= 140 secs

Therefore rounds completed are 3.5

Hence displacement is equal to the diagonal of square which is 10x2^½

3) both a and b are false
