$103. A thin convex lens L (refractive index =1.5 ) is placed on a plan$

103. A thin convex lens $L$ (refractive index $= 1.5$ ) is placed on a plane mirror $M$ . When a pin is placed at $A$ , such that $O A = 18 cm$ , its real inverted image is formed at $A$ itself, as shown in figure. When a liquid of refractive index $m u_{l}$ is put between the lens and the mirror, the pin has to be moved to $A^{p r im e}$ , such that $O A^{p r im e} = 27 cm$ , to get its inverted real image at $A^{p r im e}$ itself.
