Let the circles C1: x2+y2=9 and C2: (x−3)2+(y−4)2=16, intersect at the points X and Y. Suppose that another circle C3: (x−h)2+(y−k)2=r2 satisfies the following conditions:
(i) centre of C3 is collinear with the centres of C1 and C2.
(ii)C1 and C2 both lie inside C3, and
(iii) C3 touches C1 at M and C2 at N
Let the line through X and Y intersect C3 at Z and W, and let a common tangent of C1 and C3 be the tangent to the parabola x2=8αy.
