When we take scalar product of a vector by itself (self product) the result gives the:
Correct answer: C. Square of the magnitude of the vector
- A. Magnitude of the vector
- B. Square root of the magnitude of the vector
- C. Square of the magnitude of the vector
- D. Same vector
Explanation
When you take the scalar product (dot product) of a vector with itself, also known as the self-product, the result is the square of the magnitude (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.
