  1. A \(x+3 z=10\)
  2. B \(x+3 z=0\)
  3. C \(3 x+z=6\)
  4. D \(3 x-z=0\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(3 x-z=0\)

Step-by-step Solution

Detailed explanation

\(\overrightarrow{ n }=\hat{ j } \times(\hat{ i }+2 \hat{ j }+3 \hat{ k })\) \(=-3 \hat{i}+0 \hat{j}+\hat{k}\) So, \((-3)(x-1)+0(y-2)+(1)(z-3)=0\) \(\Rightarrow-3 x+z=0\) Alternate : Required plane is…
