If L . M = M . L , then we can say:
Correct answer: A. Scalar product is commutative
- A. Scalar product is commutative
- B. Scalar product is positive
- C. Scalar product is negative
- D. None of these
Explanation
he scalar product (dot product) of two vectors is commutative. This means that for any two vectors L and M, the scalar product is the same regardless of the order in which you take the dot product: L.M = M.L

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.
