An expansible balloon filled with air is floating on the top surface of a lake, with `2//3` of its volume is submerged in water. How deep should it be sunk in water without changing the temperature of air in it, in order that it is just in equilibrium, neither sinking nor rising further? Height of water barometer `= 10 m`.

An expansible balloon filled with air floats on the surface of a lake with 2//3 of its volume submerged. How deep must it be sunk in the water so that it is just in equilibrium neither sinking further nor rising? Is is assumed that the temperature of the water is constant & that the height of the water barometer is 9 meters.

A sealed balloon, filled with air, floats in water with (1)/(3) of its volume submerged. It was found that if it is pushed inside water at a depth h, it remains in equilibrium, neither sinking nor rising. Find h. Given that height of water barometer is 10m and temperature is constant at all depth.

An air bubble rises from the bottom to the surface of lake and it is found that its diameter is duubled. If the height of water barometer is 11m , the depth of the lake in maters is

A balloon filled with air is just floating in water in a beaker, as shown in fig. If the balloon is submerged more by a small distance and released, then the balloon will move up or move down to bottom or remains at the same location where released. Explain.

A block of wood floats in water with (4//5)th of its volume submerged. If the same block just floats in a liquid, the density of liquid in (kg m^(-3)) is

A balloon made of rubber and filled with air is floating in water in such a way that its top surface just coincides with the level of the water. If the balloon is gently pushed a short distance downward in water and then released, it will
