The magnitude of a vector C is represented as _.
Correct answer: B. The size or length of the vector
- A. The direction of the vector
- B. The size or length of the vector
- C. The components of the vector
- D. The origin of the vector
Explanation
When we talk about the magnitude of a vector, we are referring to the size or length of the vector. It is represented by a scalar value and is obtained using mathematical operations like the Pythagorean theorem. Geometrically, vectors are represented by arrows, with the end marked by an arrowhead. Options A, C, and D are incorrect because they do not represent the concept of magnitude, which is specifically related to the size or length of the 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.
