Question

The normal at p and Q on the parabola y2 = 4ax meet on the parabola. Then the chord PQ passes through the
point.​

Answer 1

Answer:

Step-by-step explanation:Correct option d by = 2ax - a Explanation :Let P = at12 2at1 and Q = at22 2at2 so thatt = at1t2 at1 + t2 The equation of the chord PQ isy - 2at1 = 2/t1 + t2 x - at12 The chord PQ passes through the point -a b. So Suppose x y = T = [at1t2 at1 + t2]. Thenx = at1t2 and y = at1 + t2Substituting the values of x and y in Eq. 1 we haveby/a - 2x + 2 = 0by = 2ax - a
