An Iron Block of Density ρFe and of Volume L3

question 35

Multiple Choice

An iron block of density ρFe and of volume l3 is immersed in a fluid of density ρfluid. 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 = (ρFe − ρfluid)ghl2.
• B)w = (ρfluid − ρFe)gl3.
• C)w = (ρFe − ρfluid)gl3.
• D)w = (ρFe + ρfluid)ghl2.
• E)w = (ρFe + ρfluid)gl3.
