If \(P Q\) is a focal chord of the parabola \(y^2=4 x\) with focus \(S\) and \(P=(4,4)\), then \(S Q=\)
- A 2
- B \(\frac{5}{4}\)
- C 5
- D \(\frac{3}{2}\)
Answer & Solution
Correct Answer
(B) \(\frac{5}{4}\)
Step-by-step Solution
Detailed explanation
\(P Q\) is focal chord of parabola \(y^2=4 x\) focus \(S(1,0)\) and \(P(4,4)\) We know that, Length of Semi-latus rectum is Harmonic mean of \(P S\) and \(S Q\)…
