Finding downward force on immersed object

[QUOTE="haruspex, post: 6866585, member: 334404"] I remain bewildered by your explanations. What do you mean by "downward force from the water"? We cannot know and do not care what the force from water pressure is on top of the objects. Is it possible that the TA is using ##F_i## to mean something else? The only way the TA's algebra works is if ##F_i## is the upward force applied by the net. Even then, it takes two mistakes that cancel … unless B is defined as positive down. If the net is slack then what is holding the objects up? Seems they must be less dense than water and are floating, in which case we cannot determine their density because some of their volume is not displacing water. Putting all that aside, can you tell me how you’re measuring the ##F_i## in your table? [/QUOTE]
