JEE Mains · Maths · STD 12 - 11. three dimension geometry

माना \(L\), समतलों \(\overrightarrow{ r } \cdot(\hat{ i }-\hat{ j }+2 \hat{ k })=2\) तथा \(\overrightarrow{ r } \cdot(2 \hat{ i }+\hat{ j }-\hat{ k })=2\) की प्रतिच्छेदन रेखा है। यदि बिन्दु \((1,2,0)\) से रेखा \(L\) पर डाले गए लम्ब का पाद \(P (\alpha, \beta, \gamma)\) है, तो \(35(\alpha+\beta+\gamma)\) का मान बराबर है-

  1. A \(134\)
  2. B \(119\)
  3. C \(143\)
  4. D \(101\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(119\)

Step-by-step Solution

Detailed explanation

\(P_{1}: x-y+2 z=2\) \(P_{2}=2 x+y-3=2\) Let line of Intersection of planes \(P_{1}\) and \(P_{2}\) cuts \(x y\) plane in point \(Q\). \(\Rightarrow \quad z\)-coordinate of point \(Q\) is zero \(\Rightarrow x-y=2\) and \(2 x+y=2\} \Rightarrow x=\frac{4}{3}, y=\frac{-2}{3}\)…
