AP EAMCET · Maths · Parabola
If the straight line \(y=m x+c\) is parallel to the axis of the parabola \(y^2=l x\) and intersects the parabola at \(\left(\frac{c^2}{8}, c\right)\), then the length of the latusrectum is
- A 2
- B 3
- C 4
- D 8
Answer & Solution
Correct Answer
(D) 8
Step-by-step Solution
Detailed explanation
Here, length of latusrectum \(=l\) Since, point \(\left(\frac{c^2}{8}, c\right)\) is the point of intersection of parabola and the line \(y=m x+c\) then it will satisfy the equations.…
