Vedclass · Answer

(B) physical quantity is defined as a vector only if it possesses both magnitude and direction $AND$ follows the laws of vector addition (e.g.,the parallelogram law).Physical quantities like time,pressure,surface tension,and electric current possess a specific direction but do not follow the laws of vector addition.Therefore,a physical quantity having a direction does not necessarily have to be a vector; it may or may not be a vector.
