The diver has the least gravitational potential energy at position

Question

Hi @mcsvision2008! This question with density and buoyancy force in water with Archimedes's Principle. $$F _{buoy}=\left( V _{displaced fl.}\right)\left( \rho _{fluid} \right) \left( g \right)=\left( V _{object sub.} \right)\left( \rho_{fluid} \right)\left( g \right)$$

So, when there is least gravitational energy, U, there will be max Fb. Therefore, when$$F_{buoy}=U \rightarrow V(\rho)(g)=mgh$$ this is what I believe the answer should be based on the information. Can you provide more information?
