Question
If θ be the angle subtended at the focus by the normal chord at the point (λ,λ ),λ ≠ 0 on the parabola y2 = 4ax, then equation of the line through (1, 2) and making and angle θ with x-axis is
- x = 1
- y = 2
- x + 2y – 3 = 0
- None of these
The correct answer is: x = 1
For P point : at2 = 2at 
t = 2
P : (4a, 4a)
Q : (9a, – 6a) θ = 90º
