1.	Let a circle x2+y2−2x−3=0 touches the directrix of a parabola and passes through end points of latus rectum of the same parabola. If latus rectum of the parabola is chord of maximum length with respect to given circle and equation of parabola is y2=kx, then k=
Answer» Let a circle $x^{2} + y^{2} - 2 x - 3 = 0$ touches the directrix of a parabola and passes through end points of latus rectum of the same parabola. If latus rectum of the parabola is chord of maximum length with respect to given circle and equation of parabola is $y^{2} = k x$ , then $k =$
