The null-vector has _ magnitude.
Correct answer: C. Zero
- A. Four
- B. Five
- C. Zero
- D. Six
Explanation
The null vector, also known as the zero vector, has zero magnitude because it has no direction and doesn't contribute to the length or size of a vector space. Mathematically, the magnitude of a vector is a measure of its length, and for the null vector, there is no displacement in any direction, resulting in a magnitude of zero.

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.
