A convex lens of focal length `15 cm` is placed in front of a convex mirror. Both are coaxial and the lens is `5 cm` from the apex of the mirror. When an object is placed on the axis at a distance of `20 cm` from the lens, its is found that image coincides with the object. Calculate the radius of curvature of mirror.
