If a plane \(P\) passes through the points \((1,0,0),(0,1,0)\) and makes an angle \(\frac{\pi}{4}\) with the plane \(x+y=3\), then the direction ratios of a normal to that plane \(P\) is
- A \(1, \sqrt{2}, 1\)
- B \(1,1, \sqrt{2}\)
- C \(1,1,2\)
- D \(\sqrt{2}, 1,1\)
Answer & Solution
Correct Answer
(B) \(1,1, \sqrt{2}\)
Step-by-step Solution
Detailed explanation
Let the direction ratio of normal to the plane \(P\) is \((a, b, c)\). \(\because\) equation of another given plane \(x+y=3\) having direction ratio of normal \(=(1,1,0)\)…
