Thus, it is experiencing the greatest buoyant force. The ping-pong ball, which is small and only partly submerged, is displacing the least amount of water. Thus, it experiences the least buoyant force. The wood block is in the middle of the two. 2) All three objects displace some water. All three objects experience a buoyant force. The objects are submerged in fresh water and hang attached by a lightweight string, as shown in the figure. Apatite= 3.2 x 10 3 kg/m 3. Amalgam= 11.6 x 10 3 kg/m 3. Titanium= 4.5 x 10 3 kg/m 3. Which of the three objects experiences the greatest buoyant force? (a) The object made of apatite (b) The object made of amalgam (c) The object made. Video Transcript. Uh, why is it that the buoyant force on a submarine that submerged is a lot greater than when it's floating? And the reason for this is that when it's floating, less of its volume is, you know, under water. Sep 28, 2018 The buoyant force is an upward force that opposes the downward force of gravity. The magnitude of the buoyant force determines whether an object will sink, float, or rise when submerged in a fluid. An object will sink if the gravitational force acting on it is greater than the buoyant force. Buoyant Force: Buoyancy is the tendency of a fluid to exert an upward force on an object which is submerged in it. The force that is exerted by the fluid is called the 'buoyant force'.
