A thin equiconvex lens made of glass of refractive index `3//2` and of focal length `0.3m` in air is sealed into an opening at one end of a tank filled with water `(mu=(3)/(2))`. On the opposite side of the lens, a mirror is placed inside the tank on the tank wall perpendicular to the lens axis as shown in Figure. The separation between the lens and mirror is `0.8m. ` A small object is placed outside the tank in front of the lens at a distance oa `0.9m` from the lens along its axis. Find the position (relative to lens) of the image of the object formed by the system.
