Let \(\mathrm{A}=(-3,-2,7)\) and \(\mathrm{B}=(3,1,-2)\). Let a plane perpendicular to the line segment \(A B\) divide \(A B\) in the ratio \(2: 1\). Then the intercept made by the plane on \(y\)-axis is
- A \(\frac{-1}{2}\)
- B \(\frac{1}{3}\)
- C \(2\)
- D \(-1\)
Answer & Solution
Correct Answer
(D) \(-1\)
Step-by-step Solution
Detailed explanation
Let plane \(\mathrm{P}\) divides Line \(\mathrm{AB}\) at \(\mathrm{Q}\) in ratio 2:1 \(\Rightarrow Q=(1,0,1)\) Now, equation of plane passing through \((1,0,1)\) with DRS \((6,3,-9)\) is…
