3. Does the phrase "direction of zero vector" have physicalsignificance? Discuss in terms of velocity, force etoc.

Answer»

Although the existence of null vector is essential for vector algebra as it acts as the essential additive inverse, there is no physical significance of null vector. Actually its direction is undeterminable.If a man applies 0 N of force, he is not applying any force so its direction can’t possibly have any physical significance.
