If \(P=(0,1,2), Q=(4,-2,1)\) and \(O=(0,0,0)\) then \(\angle \mathrm{POQ}=\)
- A \(\frac{\pi}{6}\)
- B \(\frac{\pi}{4}\)
- C \(\frac{\pi}{3}\)
- D \(\frac{\pi}{2}\)
Answer & Solution
Correct Answer
(D) \(\frac{\pi}{2}\)
Step-by-step Solution
Detailed explanation
\(P=(0,1,2), Q=(4,-2,1) \text { and } O=(0,0,0)\) Equation of line \(O P, \frac{x}{0}=\frac{y}{1}=\frac{z}{2}\) Equation of line \(O Q, \frac{x}{4}=\frac{y}{-2}=\frac{z}{1}\)…
