From the point (15,12), three normals are drawn to the three co-normals point 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)

From the point P(h, k) three normals are drawn to the parabola x^(2) = 8y and m_(1), m_(2) and m_(3) are the slopes of three normals Find the algebraic sum of the slopes of these three normals.

From the point P(h, k) three normals are drawn to the parabola x^(2) = 8y and m_(1), m_(2) and m_(3) are the slopes of three normals If two of the three normals are at right angles then the locus of point P is a conic, find the latus rectum of conic.

Co Normal Points

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
