If the chord through \((1,-2)\) cuts the curve \(3 x^2-y^2-2 x+\) \(4 y=0\) at \(P\) and \(Q\), then the angle subtended by \(P Q\) at the origin is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(90^{\circ}\)
Answer & Solution
Correct Answer
(D) \(90^{\circ}\)
Step-by-step Solution
Detailed explanation
Let \(P Q\) subtend the angle \(\theta\) at the origin. \(\Rightarrow \angle \mathrm{POQ}=\theta\) Let the slope of line is \(\mathrm{m}\). \(\therefore\) The equation of line is \(y+2=m(x-1)\)…
