MCQ
What is the angle between $(\vec{P}+\vec{Q})$ and $(\vec{P} \times \vec{Q})$
- A$\pi$
- ✓$\frac{\pi}{2}$
- C$\frac{\pi}{4}$
✓
Answer
Correct option: B.
$\frac{\pi}{2}$
(b) Vector $(\vec{P}+\vec{Q})$ lies in a plane and vector $(\vec{P} \times \vec{Q})$ is perpendicular to this plane i.e. the anglebetween given vectors is $\frac{\pi}{2}$.
