PQ is a double ordinate of the parabola `y^2 = 4ax`. If the normal at P intersect the line passing through Q and parallel to axis of x at G, then locus of G is a parabola with -

PQ is a double ordinate of a parabola y^(2)=4ax. Find the locus of its points of trisection.

bar(PQ) is a double ordinate of the parabola y^2=4ax ,find the equation to the locus of its point of trisection.

overline(PQ) is a double ordinate of the parabola y^(2) = 4ax ,find the equation to the locus of its point of trisection .

PQ is a normal chord of the parabola y^2 =4ax at P, A being the vertex of the parabola. Through P, a line is drawn parallel to AQ meeting the x-axis at R. Then the line length of AR is

PC is the normal at P to the parabola y^2=4ax, C being on the axis. CP is produced outwards to disothat PQ =CP ; show that the locus of Q is a parabola.

PC is the normal at P to the parabola y^2=4ax, C being on the axis. CP is produced outwards to Q so that PQ =CP ; show that the locus of Q is a parabola.
