Question

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:

Both the statements are incorrect.

Step by step explanation:

(a) Displacement can be zero.

If the object comes back to the starting point then the displacement will be zero as displacement is the shortest path from the initial point to the final point but if the initial point and the final point are same then the Displacement will be zero.

(b) Its magnitude is lesser than the distance travelled by the object.

Distance is the actual path from the initial point to the final point. But displacement is the shortcut to cover the actual distance. So, it is not possible that displacement is greater than distance.

Answer 2

Explanation:

Both statements are incorrect, as displacement can be zero . For example, when a body is travelling in uniform circular motion and returning to same point as that of its starting point.

Also the magnitude of displacement is always less or equal to the distance travelled by the body. Displacement can never be greater than the distance, as it is defined as the shortest distance from the initial to final position of object.

Hence, no statement is true for displacement.
