A concave mirror of radius of curvature 60 cm is placed at the bottom of a tank, containing water up to height of 20 cm. The mirror faces upwards with its axis vertical. Solar light falls normally on the surface of water and the image of sun is formed. If u=4/3, then with the observer in air, the distance of the image from the surface of water is
