Geometrical Optics

A point object, 'O' is placed in front of two thin symmetrical coaxial convex lenses \(\mathrm{L}_{1}\) and \(\mathrm{L}_{2}\) with focal length \(24 \mathrm{~cm}\) and \(9 \mathrm{~cm}\) respectively. The distance between two lenses is \(10 \mathrm{~cm}\) and the object is placed \(6 \mathrm{~cm}\) away from lens \(\mathrm{L}_{1}\) as shown in the figure. The distance between the object and the image formed by the system of two lenses is __________ \(\mathrm{cm}\).
