Q70.The point of intersection of the normals to the parabola y2 = 4x at the ends of its latus rectum is : (1) (0, 2) (2) (3, 0) (3) (0, 3) (4) (2, 0)

What This Question Tests

This problem involves finding the coordinates of the ends of the latus rectum for a parabola, writing the equations of the normals at these points, and then solving them simultaneously to find their intersection point.

Concepts Tested

Equation of a parabola (y^2=4ax)Latus rectum of a parabolaEquation of normal at a point

Formulas Used

Coordinates of ends of latus rectum: (a, ยฑ2a)

Equation of normal at (x1, y1) to y^2=4ax: y-y1 = -y1/(2a) * (x-x1)
