The scalar product of a vector A is given by:
Correct answer: D. None of the above
- A. A cos θ
- B. A sin θ
- C. A tan θ
- D. None of the above
Explanation
The scalar product of a vector A can be found by multiplying its magnitude by itself, which is the square of the magnitude of vector A. Mathematically, if vector is denoted as A, then its scalar product is A.A = AA cos 0° = A²None of the provided options correctly represent this calculation, making 'None of the above' the correct choice.

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.
