MCQ
If a vector $\vec{A}$ is parallel to another vector $\vec{B}$ then the resultant of the vector $\vec{A} \times \vec{B}$ will be equal to
- A$A$
- B$\vec{A}$
- ✓Zero vector
- DZero
✓
Answer
Correct option: C.
Zero vector
(c) $\vec{A} \times \vec{B}=A B \sin \theta \hat{n}$for parallel vectors $\theta=0^{\circ}$ or $180^{\circ}, \sin \theta=0$$\therefore \vec{A} \times \vec{B}=\hat{0}$
