1 The figure , on the right, shows a jar filled with two liquids of densities ρ and ρ/2 that do not mix. A cylinder made of a material of density 3ρ/4 is held in the jar at various depths starting from the position where the lower surface of the cylinder touches the upper surface AB of the liquid. Which of the following schematic curves best describes the buoyancy force F on the cylinder as a function of the displacement h from the starting position?
