A cylindrical container has cross sectional area of
0.20 m2
and is open at the top. At the bottom, it
has a small hole (A) kept closed by a cork. There
is an air balloon tied to the bottom surface of the
container. Volume of balloon is 2.2 litre. Now
water is filled in the container and the balloon
gets fully submerged. Volume of the balloon
reduces to 2.0 litre. The cork is taken out to
open the hole and at the same moment the whole
container is dropped from a large height so as
to fall under gravity. Assume that the container
remains vertical. Find the change in level of water
inside the falling container 2 second after it starts
falling.
