A thin bi-convex lens made up of glass of refractive index `3//2` is placed is front of a plane mirror. The space between the lens and the mirror is filled with water of refractive index `4//3` . The radii of curvatures of the lens are `R_(1)=15cm` and `R_(2)=25 cm ` .  A point object is placed at distance x from the surface whose curvature is `R_(1)`. The distance x is greater than the separation between the lens and the mirror. Find the value of x so that image must coincide with the object.
