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

यदि दो परस्पर लंब समतलों \(2 x + ky -5 z =1\) तथा \(3 kx - ky + z =5, k <3\) के प्रतिच्छेदन से होकर जाने वाले समतल \(P\) का धनात्मक \(x\)-अक्ष पर अंतःखंड लंबाई एक है, तो \(P\) का \(y\)-अक्ष पर अंतः खंड है

  1. A \(\frac{1}{11}\)
  2. B \(\frac{5}{11}\)
  3. C \(6\)
  4. D \(7\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(7\)

Step-by-step Solution

Detailed explanation

Two given planes mutually perpendicular \(2(3 k )+ k (- k )+(-5) 1=0\) \(k =1,5\) but \(k <3\) So \(k =1\) Plane passing through these planes is \(2 x+y-5 z-1+\lambda(3 x-y+z-5)=0\)…
