माना रेखा \(\ell: \mathrm{x}=\frac{1-\mathrm{y}}{-2}=\frac{\mathrm{z}-3}{\lambda}, \lambda \in \mathbb{R}\) समतल \(P: x+2 y+3 z=4\) को बिंदु \((\alpha, \beta, \gamma)\) पर मिलती है। यदि रेखा \(\ell\) तथा समतल \(\mathrm{P}\) के बीच का कोण \(\cos ^{-1}\left(\sqrt{\frac{5}{14}}\right)\) है, तो \(\alpha+2 \beta+6 \gamma\) बराबर है

  1. A \(11\)
  2. B \(10\)
  3. C \(12\)
  4. D \(13\)

Answer & Solution

Correct Answer

(A) \(11\)

Step-by-step Solution

Detailed explanation

\(\ell: x =\frac{ y -1}{2}=\frac{ z -3}{\lambda}, \lambda \in R\) DR's of line \(\ell(1,2, \lambda)\) DR's of normal vector of plane \(P: x+2 y+3 z=4\) are \((1,2,3)\) Now, angle between line \(\ell\) and plane \(P\) is given by…
