In graphical addition of vectors
Correct answer: B. The order of vectors is not to be altered
- A. The position of vectors is unimportant
- B. The order of vectors is not to be altered
- C. The direction of resultant is unknown
- D. The position of vectors is important
Explanation
Vector Addition Using Graphical Method The graphical method to add vectors is the head-to-tail method. The starting point of the vector is represented by the tail of the vector, and the pointed end of the arrow is represented by the tip or head of the vector. In head to tail rule the order of vectors is not to be changed otherwise the answer would be considered wrong.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
