An Iron Block of Density ρ_Fe and of Volume L³

question 32

Multiple Choice

An iron block of density ρ_Fe and of volume l³ is immersed in a fluid of density ρ_fluid. The block hangs from a scale which reads W as the weight. The top of the block is a height h below the surface of the fluid. The correct equation for the reading of the scale is

• A) W = (ρ_Fe − ρ_fluid)ghl².
• B) W = (ρ_fluid − ρ_Fe)gl³.
• C) W = (ρ_Fe − ρ_fluid)gl³.
• D) W = (ρ_Fe + ρ_fluid)ghl².
• E) W = (ρ_Fe + ρ_fluid)gl³.
