P is a point on the parabola y2=4 a x(a0) whose vertex is A. PA is produced to meet the directrix in D and M is the foot of the perpendicular from P on the directrix. If a circle is described on MD as a diameter then it intersects the X-axis at a point whose co-ordinates are:

Question

P is a point on the parabola y2=4 a x(a>0) whose vertex is A. PA is produced to meet the directrix in D and M is the foot of the perpendicular from P on the directrix. If a circle is described on MD as a diameter then it intersects the X-axis at a point whose co-ordinates are: (A) (-3 a, 0) (B) (- a , 0) (C) (-2 a , 0) (D) ( a , 0)
