A thin equiconvex lens of glass of refractive index \( \mu=3 / 2 \) \( \& \) of focal length \( 0.3 \mathrm{~m} \) in air is sealed into an opening
\( P \) at one end of a tank filled with water \( (\mu=4 / 3) \). On the W. 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 the mirror is \( 0.8 \mathrm{~m} \). A small object is placed outside the tank - in front of the lens at a distance of \( 0.9 \mathrm{~m} \) from the lens along its axis. Find the position (relative to the lens) of the image of the object formed by the system.
