Shown in the figure are two hollow cubes C1 and C2 of negligible mass partially filled (depicted by darkened area) with liquids of densities ρ1 and ρ2, respectively, floating in water (density ρw). The relationship between ρ1, ρ2 and ρw is
1
ρ2 < ρw < ρ1
2
ρ2 < ρ1 < ρw
3
ρ1 < ρ2 < ρw
4
ρ1 < ρw < ρ2
