2. A circle, with its centre at the focus of the parabola y? - 4ax and touching its directrix, intersects the parabola at the point (A) (a, 2a) (B) (a,-2a) (D) a/2a 2a

The focus of the parabola y^(2) = - 4ax is :

If a circle drawn with radius 1 unit and whose centre is the focus of the parabola y^(2)=4x touches the parabola at

Foot of the directrix of the parabola y^(2) = 4ax is the point

If the focus of a parabola is (0,-3) and its directrix is y=3, then its equation is

If the focus of a parabola is at (0,-3) and its directrix is y = 3, then its equation is

Consider a circle with its centre lying on the focus of the parabola,y^(2)=2px such that it touches the directrix of the parabola.Then a a point of intersection of the circle & the parabola is:

If a line x+ y =1 cut the parabola y^2 = 4ax in points A and B and normals drawn at A and B meet at C. The normals to the parabola from C other than above two meets the parabola in D, then point D is : (A) (a,a) (B) (2a,2a) (C) (3a,3a) (D) (4a,4a)
