एक ऐसे समतल का समीकरण, जिस पर रेखा \(\frac{ x }{2}=\frac{ y }{3}=\frac{ z }{4}\) स्थित है तथा जो एक अन्य समतल जिसमें रेखाएँ \(\frac{ x }{3}=\frac{ y }{4}=\frac{ z }{2}\) तथा \(\frac{ x }{4}=\frac{ y }{2}=\frac{ z }{3}\) स्थित हैं, के लंबवत् है

  1. A \(x + 2y - 2z = 0\)
  2. B \(x - 2y + z = 0\)
  3. C \(5x + 2y - 4z = 0\)
  4. D \(3x + 2y - 3z = 0\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(x - 2y + z = 0\)

Step-by-step Solution

Detailed explanation

Vector along the normal to the plane containing the lines \(\frac{x}{3}=\frac{y}{4}=\frac{z}{2}\) and \(\frac{x}{4}=\frac{y}{2}=\frac{z}{3}\) \(\left( {8{\rm{ }}\hat i - \hat j - 10{\rm{ }}\hat k} \right).\) Vector perpendicular to the vectors \(2\hat i + 3\hat j + 4\hat k\) and…
