The cross product ( A × B ) of two non-zero parallel vectors is equal to
Correct answer: C. Zero
- A. AB sin θ n
- B. AB cos θ
- C. Zero
- D. AB
Explanation
The cross product ( A × B ) of two non-zero parallel vectors is equal to zero. This is because the cross product is defined as the product of the magnitudes of the vectors and the sine of the angle between them. When the vectors are parallel, the angle between them is either 0 degrees or 180 degrees, and the sine of 0 degrees (or 180 degrees) is zero.

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.
