A concave lens focal length 10 cm is placed on the axis of concave mirror of 10 cm radius at a distance of 5 cm from the mirror. An object is placed so that the light coming from it first passes through the lens, the gets reflected from the mirror, again passes through the lens to form an inverted image coincident with the object itself. Determine the position of the object.
