Question

A steel beam is suspended completely under water by a cable that is attached to one end of the beam, so it hangs vertically. Another identical beam is also suspended completely under water, but by a cable that is attached to the center of the beam, so it hangs horizontally. Which beam, if either, experiences the greater buoyant force? Neglect any change in water density with depth.

Answer 1

Both the beams shall experience identical buoyant forces

Step-by-step explanation:

The buoyant force that acts on an object completely immersed in water is given by the weight of water that the object displaces. Since volume of the 2 beams are the same since they are identical and since there is no variation of density along with depth thus we expect the buoyant forces on the 2 beams to be identical.
