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