JEE Main 2022 Mathematics question
Let the normal at the point P on the parabola pass through the point (5, −8). If the tangent at P to the parabola intersects its directrix at the point Q, then the ordinate of the point Q is :
Answer: (2)
Solution
Write , 2at) with a = 3/2. The normal at P is y = −tx + ; passing through (5, −8): −8 = −5t + , so , i.e. 2)(3t^{2}$ - 6t +
