The figure shows an arrangement of an equi-convex lens and a concave mirror. A point object O is placed on the principal axis at a distance `40 cm` from the lens such that the final image is also formed at the position of the object. If the radius of curvature of the concave mirror is `80 cm,` find the distance d. Also draw the ray diagram. The focal length of the lens in air is `20 cm.
