The triangle PQR of area ‘A’ is inscribed in the parabola y2 = 4ax such that the P lies at the vertex of the parabola and the base QR is a focal chord. The modulus of the difference of the ordinates of the points Q and R is :
- \(\frac{A}{2 a}\)
- \(\frac{A}{a}\)
- \(\frac{2 A}{a}\)
- \(\frac{4 A}{a}\)
Answer
(C) 2 A a
