) The fish and the observer are on the principal axis of the lens. The fish moves up with constant velocity 100 cm/s . initially it was at adepth of 44.0 cm. The velocity with which the fish appears to In the given figure, a stationary observer O looking at a fish (in water of,µ =4/3) through a converging lens of local length 90 cm. The lens is allowed to fallfreely from a height 62.0 cm with its axis vertical. move to the observer at t= 0.2 sec is (x + 3/4) m/s. Find the value of x( g = 10 m/s2)
