A point object, ' $\displaystyle O$ ' is placed in front of two thin symmetrical coaxial convex lenses $\displaystyle L_1$ and $\displaystyle L_2$ with focal length $\displaystyle 24$ cm and $\displaystyle 9$ cm respectively. The distance between two lenses is $\displaystyle 10$ cm and the object is placed $\displaystyle 6$ cm away from lens $\displaystyle \mathrm{L}_1$ as shown in the figure. The distance between the object and the image formed by the system of two lenses is $\displaystyle \_\_\_\_$ cm .
