The vertex V of the parabola `y ^(2) = 4ax` and two points on the parabola together with a point P form a square. The coordinates of P are

Normal at a point P on the parabola y^(2)=4ax meets the axis at Q such that the distacne of Q from the focus of the parabola is 10a. The coordinates of P are :

The slopes of the normal to the parabola y^(2)=4ax intersecting at a point on the axis of the parabola at a distance 4a from its vertex are in

If the parabola y^(2) = 4ax passes through the point (4, 1), then the distance of its focus the vertex of the parabola is

If the parabola y^(2) = 4ax passes through the point (4, 1), then the distance of its focus the vertex of the parabola is

A tangent to the parabola y^2 + 4bx = 0 meets the parabola y^2 = 4ax in P and Q. The locus of the middle points of PQ is:
