1anyone??
there is a cylindrical container of depth h. Its bottom is silvered. A point object is fixed at the mouth of the container. Initially the container is filled with water( mu=4/3) . Now the orifice at the bottom is opened. Find the time after which the separation between object and image will be (7/4)h. Cross sectional area of container is A and that of orifice is 'a'.(a<<A)
my doubt is that when lets say at time 't' height of water is 'x' . Then what is the expression for apparent distance of object from mirror?? rest of the integration stuff I can do.

if I follow the above diagram
at time t apparent distance of object from mirror comes out to be
(4/3)(h-x) + x
which gives a totally wrong ans
what is the problem in the above diagram???
