Three identical suspended cylinders submerged to different depths in a fluid of uniform density.
Three identical suspended cylinders submerged to different depths in a fluid of uniform density.
Three identical solid metal cylinders of mass \(m\) and volume \(V\) are suspended from ideal spring scales and lowered into identical beakers containing an incompressible fluid of uniform density \(\rho\). In Case 1, the cylinder is held half-submerged. In Case 2, the cylinder is fully submerged with its top surface at a depth \(d\) below the fluid surface. In Case 3, the cylinder is fully submerged with its top surface at a depth \(2d\) below the fluid surface without touching the bottom of the beaker. Which of the following correctly ranks the scale readings \(F_1\), \(F_2\), and \(F_3\) from greatest to least?
