If the force of gravity(weight)on a scuba diver is 600N,what should the buoyant force be if the diver wants to

Question

A)Desend
B) Rise to the surface

Answer 1

A. to descend it must be less than 600N
B. Rise to the surface the buoyant factor must be equal to or greater than your 600N.of gravity.
A buoyancy of equal performance means-Neutral Buoyancy were one can dive or raise with little applied force from the driver.It would be gravity of 600N to buoyancy of 600N applied to counter gravity.

Answer 2

This is a simple equilibrium problem. The force of gravity is straight down; the buoyant force is straight up. The net force is buoyancy minus gravity. If it is positive, the diver with rise. If it is negative, the diver will descend. If it is zero, the diver is neutrally buoyant and will maintain current depth assuming water conditions don't change.

summary:
Force (Buoyant) > 600N --> rise
Force (Buoyant) < 600N --> sink
