Vedclass · Answer

(A) vector is a physical quantity that has both magnitude and direction. When we represent a vector as $\vec{A} = A_x\hat{i} + A_y\hat{j} + A_z\hat{k}$,the components $(A_x, A_y, A_z)$ depend on the orientation of the coordinate axes. However,the vector sum $\vec{P} + \vec{Q} + \vec{R}$ represents a resultant vector,which is a physical entity independent of the coordinate system used to describe it. Options $B$ and $C$ represent components or partial sums that change if the axes are rotated. Therefore,the vector sum $\vec{P} + \vec{Q} + \vec{R}$ is invariant under coordinate transformation.
