SUMMARY
The discussion centers on calculating the potential energy associated with the buoyant force acting on a submerged sphere in water. The key formula derived is the total potential energy, expressed as pgvd - mgd, where p is the density of the sphere, g is the acceleration due to gravity, v is the volume of the sphere, and d is the depth below the surface. It is emphasized that the buoyant force is equal to the weight of the water displaced and that only changes in potential energy are significant in this context. The importance of correctly identifying the densities involved is also highlighted.
