The product of two vector is called scalar or dot product when they give_.
Correct answer: B. Scalar quantity
- A. Vector quantity
- B. Scalar quantity
- C. Negative quantity
- D. Positive quantity
Explanation
A scalar is a physical quantity that is completely defined by its magnitude. A dot product is the product of two vectors by taking the component of the second vector in the direction of the first vector. In the dot product of vectors, we see that only magnitude is present without any direction, which shows that result is a scalar quantity.Hence, the Dot Product of vectors is a scalar quantity.

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.
