The acute angle between the two lines whose direction ratios are given by \(l+m-n=0\) and \(l^2+m^2-n^2=0\), is
- A \(0\)
- B \(\frac{\pi}{6}\)
- C \(\frac{\pi}{4}\)
- D \(\frac{\pi}{3}\)
Answer & Solution
Correct Answer
(D) \(\frac{\pi}{3}\)
Step-by-step Solution
Detailed explanation
Given that \[ l+m-n=0 \] and \[ l^2+m^2-n^2=0 \] From equaion (i) \(l=-(m-n)\) Putting in equation (ii), we get…
