Question

can displacement be zero if yes give two examples​

Answer 1

$\huge{\red{ \fbox{↪ Answer : }}}$

Yes it can be zero. It happens if path is circular.

Answer 2

Answer:

A

Yes. For example, a car travels from point A to B and then comes back. Suppose AB=5m. In this case, distance travelled is 10m, while the displacement is zero.

Displacement can be zero even when distance is not zero. Consider two points A and B such that AB = 5 m. When a car travels from A to B and then back from B to A, distance = 5+5 = 10 m. Displacement = Minimum distance between final(B) and initial position(B) = 0.
