Consider a parabola `y^(2)=8x` whose focus is S ,three normal's at the points P,Q,R on the parabola are concurrent at H(6,0) then value of the product SP.SQ.SR=

Consider the parabola y^(2)=8x, if the normal at a point P on the parabola meets it again at a point Q, then the least distance of Q from the tangent at the vertex of the parabola is

Consider a parabola x^2-4xy+4y^2-32x+4y+16=0 . The focus of the parabola (P) is

If the tangents at the points P and Q on the parabola y^2 = 4ax meet at R and S is its focus, prove that SR^2 = SP.SQ .

If the normals at P,Q,R of the parabola y^(2)=4ax meet in O and S be its focus,then prove that.SP.SQ.SR=a.(SO)^(2)

Normals are drawn at points P, Q are R lying on the parabola y^(2)=4x which intersect at (3, 0), then

The normals at three points P,Q,R of the parabola y^(2)=4ax meet in (h,k) The centroid of triangle PQR lies on (A)x=0(B)y=0(C)x=a(D)y=a^(*)

If y=mx+c is the normal at a point on the parabola y^(2)=8x whose focal distance is 8 units.Then |c|

If P,Q R are conormal points of a parabola y^(2)=4x where normals are drawn from (9,0), s be focus of parabola then SP.SQ.SR=
