From the point (3 0) 3- normals are drawn to the parabola `y^2 = 4x`. Feet of these normal are P ,Q ,R then area of triangle PQR is

From a point (h,k) three normals are drawn to the parabola y^2=4ax . Tangents are drawn to the parabola at the of the normals to form a triangle. The centroid G of triangle is

From the point (15,12), three normals are drawn to the parabola y^(2)=4x. Then centroid and triangle formed by three co-normals points is (A)((16)/(3),0) (B) (4,0) (C) ((26)/(3),0) (D) (6,0)

Three normals are drawn to the parabola y^(2) = 4x from the point (c,0). These normals are real and distinct when

The number of normals drawn to the parabola y^(2)=4x from the point (1,0) is

Three normals drawn to the parabola y^(2) = 4x from the point (c, 0) are real and diferent if
