AB is a chord of the parabola `y^2 = 4ax` with its vertex at A. BC is drawn perpendicular to AB meeting the axis at C.The projecton of BC on the axis of the parabola is

AB is the chord on the parabola y^(2)=4ax with its vertex at A.BC is drawn perpendicular to AB meeitng the axis at C. The projection of BC on the axis of the parabola is :

OA is the chord of the parabola y^(2)=4x and perpendicular to OA which cuts the axis of the parabola at C. If the foot of A on the axis of the parabola is D, then the length CD is equal to

AB is a focal chord of the parabola y^(2)=4ax If A=(4a,4a) then B=

The vertex A of the parabola y^(2)=4ax is joined to any point P on it and PQ is drawn at right angles to AP to meet the axis in Q. Projection of PQ on the axis is equal to

PQ is a chord ofthe parabola y^(2)=4x whose perpendicular bisector meets the axis at M and the ordinate of the midpoint PQ meets the axis at N .Then the length MN is equal to

If AB is a focal chord of the parabola y^(2)=4ax whose vertex is 0, then(slope of OA ) x (slope of OB)-

A straight line is drawn parallel to the x-axis to bisect an ordinate PN of the parabola y^(2) = 4ax and to meet the curve at Q. Moreever , NQ meets the tangent at the vertex A of the parabola at T. AT= Knp , then k is equal to
