When the multiplication of two vectors result into a vector quantity, then the product is called _.
Correct answer: A. Cross product
- A. Cross product
- B. Dot product
- C. Magnitude of two vectors
- D. None of these
Explanation
The cross product, also known as the vector product, results in a vector that is perpendicular to the two vectors being multiplied. It is denoted by a × b and can be calculated using the Right-hand Rule. The dot product of two vectors is a scalar quantity, not a vector, while the magnitude of vectors is determined using the Pythagorean theorem. Therefore, the correct answer is the Cross product.

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.
