Cross product of two vectors is zero when vectors are
Correct answer: B. Parallel to each other
- A. Perpendicular to each other
- B. Parallel to each other
- C. Can never be zero
- D. Both A and B are correct
Explanation
The correct answer is that the cross product of two vectors is zero when the vectors are parallel. This is because the sine of the angle between parallel vectors (0° or 180°) is zero, making the cross product zero. The incorrect options are based on misunderstandings of vector properties: perpendicular vectors yield a maximum cross product, not zero. The statement that the cross product can never be zero ignores the possibility of parallel vectors or zero vectors. Lastly, stating both conditions as correct is logically inconsistent as they are mutually exclusive.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
