Vectors are added according to:
Correct answer: C. Head to tail rule
- A. Left hand rule
- B. Right hand rule
- C. Head to tail rule
- D. None of the above
Explanation
When adding vectors, the head to tail rule is used in the graphical method of vector addition. This rule helps determine the direction and magnitude of the resultant vector by connecting the head of one vector to the tail of the previous one. The other options, left hand rule and right hand rule, are not applicable to vector addition and are used in electromagnetics for different purposes.

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.
