Can be called a vector.

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). For example,current has both magnitude and direction but is a scalar because it does not follow the laws of vector addition. Therefore,having a direction is a necessary but not sufficient condition for a quantity to be a vector. Thus,a physical quantity with a direction 'can be called' a vector,but it is not necessarily a vector.

Column $I$	Column $II$
$(A)$ Component along $x$-axis	$(p)$ $5 \text{ unit}$
$(B)$ Component along vector $(2 \hat{i} + \hat{j} + 2 \hat{k})$	$(q)$ $4 \text{ unit}$
$(C)$ Component along $(6 \hat{i} + 8 \hat{j} - 10 \hat{k})$	$(r)$ $0$
$(D)$ Component along $(-3 \hat{i} - 4 \hat{j} + 5 \hat{k})$	$(s)$ None
