A vector is described by magnitude as well as:
Correct answer: C. Direction
- A. Angle
- B. Distance
- C. Direction
- D. Height
Explanation
A vector is completely described by its magnitude (or length) and its direction. These two components together convey all the necessary information about a vector.

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.
