Fluid statics

Two non-mixing liquids of densities ρ and nρ (n>1)  are put in a container. The height of each liquid is h. A solid cylinder of length L and density d

 is put in this container. The cylinder floats with its axis vertical and length pL  ( 𝑝<1 ) in the denser liquid. The density d is equal to


d=density of cylinder A=area of cross-section of cylinder using law of floatation,

Using law of floatation, 

Weight of cylinder = Upthrust by two liquids
