An incompressible liquid is kept in a long conducting cylindrical container, which is closed at its top by an airtight light piston. A cylinder of length 10 cm and density 0.65 g/cm3 floats with half-length submerged in the liquid as shown in the figure. Air trapped in the cylinder has density $1.30kg/m^3.$
On placing extra weight on the piston pressure of the air in the cylinder is increased to 100 times of the initial pressure. What can you conclude?
