MCQ
Three vectors $\vec{a}, \vec{b}$ and $\vec{c}$ satisfy the relation $\vec{a} \cdot \vec{b}=0$ and $\vec{a} \cdot \vec{c}=0$. The vector $\vec{a}$ is parallel to
- A$\vec{b}$
- B$\vec{c}$
- C$\vec{b} \cdot \vec{c}$
- ✓$\vec{b} \times \vec{c}$
✓
Answer
Correct option: D.
$\vec{b} \times \vec{c}$
(d) $\vec{a} \cdot \vec{b}=0$ i.e. $\vec{a}$ and $\vec{b}$ will be perpendicular to each other $\vec{a} \cdot \vec{c}=0$ i.e. $\vec{a}$ and $\vec{c}$ will be perpendicular to each other
