# Another on Circle: It will make u round and round

Geometry Level pending

A circle M is drawn with its centre on x-axis and pass through Centre of another circle N any of whose points can be given by $$( cos (\alpha) , sin ( \alpha )$$ . A common tangent to M and N Touch the Circles at Q and R respectively . The $$Q(x,y)$$ always satisfies $$x^{2} = \lambda/ 2015$$. Then $$\lambda$$ is
