If you take 5 kg of lead and aluminum blocks and submerge in a liquid, on which of these blocks is the buoyant force greatest and why? lead, because it has a higher density then the volume is lower Aluminum, because it has lower density then the volume is higher Aluminum, because it has a higher density, then the volume is lower the same buoyant force for both materials
Question
If you take 5 kg of lead and aluminum blocks and submerge in a liquid, on which of these blocks is the buoyant force greatest and why? lead, because it has a higher density then the volume is lower Aluminum, because it has lower density then the volume is higher Aluminum, because it has a higher density, then the volume is lower the same buoyant force for both materials
Solution
The buoyant force is greatest on the aluminum block. This is because buoyant force depends on the volume of the object submerged in the liquid, not its mass or density. Since aluminum has a lower density than lead, a 5 kg block of aluminum will have a greater volume than a 5 kg block of lead. Therefore, the aluminum block displaces more liquid when submerged, resulting in a greater buoyant force.
