It should be noted that this is not homework but rather practice for an exam. Is this the place I should be asking these types of questions? 1. The problem statement, all variables and given/known data An apple is held completely submerged just below the surface of the water in a container. The apple is then moved to a deeper point in the water. Compared with the force needed to hold the apple just below the surface, what is the force needed to hold it at a deeper point? (a) larger (b) the same (c) smaller (d) impossible to determine 2. Relevant equations P=Po+ρgh 3. The attempt at a solution I thought since we know pressure increases with depth that the answer would be (a), but apparently it is (b). I do realize it is in a container, but shouldn't the pressure inside the container vary with depth? A good explanation would be greatly appreciated.
