61. Buoyancy on a Submarine 

How is the buoyancy of a submarine affected when it is submerged?

End Question:

Suppose a submarine is submerged at a particular depth in a body of seawater of constant density from the surface to the ocean floor. How would the buoyant force on the submarine compare if it were at rest appreciably deeper? More, less, or the same? Defend your answer.
