Question

The diver has the least gravitational potential energy at position

Answer 1

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

Answer 2

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?
