JEE Mains · Maths · STD 11 - 10.2 parabola,ellipse,hyperbola
If two tangents drawn from a point \(\mathrm{P}\) to the parabola \(\mathrm{y}^{2}=16(\mathrm{x}-3)\) are at right angles, then the locus of point \(\mathrm{P}\) is :
- A \(x+3=0\)
- B \(x+1=0\)
- C \(x+2=0\)
- D \(x+4=0\)
Answer & Solution
Correct Answer
(B) \(x+1=0\)
Step-by-step Solution
Detailed explanation
Locus is directrix of parabola \(x-3+4=0 \Rightarrow x+1=0\)
