Water + Eno With Balloon

A ballong filled with air is weighted so that it barely floats in water as shown in figure. When it is pushed down so that it gets submerged a short distance in water then the balloon

A stone is dropped from a balloon rising with acceleration a. The acceleration of the stone relative to the balloon is :

A balloon of radius r subtends an angle alpha at the eyes of an observer and the center of balloon from the eye is beta . Find the height of the center of the balloon from the eye of observer .

An air filled balloon is at a depth of 1 km below the water level in an ocean . The normal stress of the balloon (in Pa) is (Given, rho_("water") = 10^(3) kgm^(-3), g = 9.8 ms^(-2) and P_(atm) = 10^(5) Pa)

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 rubber balloon filled with hydrogen gas is left free in air. Then the balloon

A balloon is floating in the air. In which direction is pressure acting on the balloon?
