A beach ball is made of thin plastic. It has been inflated with air, but the plastic is not stretched. By swimming with fins on, you manage to take the ball from the surface of a pool to the bottom. Once the ball is completely submerged, what happens to the buoyant force exerted on the beach ball as you take it deeper? (a) It increases. (b) It remains constant. (c) It decreases. (d) It is impossible to determine.

A beach ball made of thin plastic is submerged in a pool. Whathappens to the buoyant force as the ball is taken from the surfaceto the bottom. The expert answer says it increases, but I do notfollow that. My thought is:
As the beach ball is taken deeper, it will compress due to theincreased pressure of the column of water above it. As itcompresses, the volume of the beach ball will decrease. As thevolume decreases, it has a smaller surface area. Since B=?fluid*g*h and h decreases, Bdecreases.
Is my thought process correct?

Rank the buoyant forces exerted on the following five objects of equal volume from the largest to the smallest. Assume the objects have been dropped into a swimming pool and allowed to come to mechanical equilibrium. If any buoyant forces are equal, state that in your ranking.

(a) a block of solid oak

(b) an aluminum block

(c) a beach ball made of thin plastic inflated with air

(d) an iron block

(e) a thin-walled sealed bottle of water
