(Buoyancy of a submerged body; compressibility of air)
A grade 4 science student inverts a cup full of air into a water tank. If it takes 1 lb of force to hold the cup down 3 inches below the surface, how much force does it take to hold the cup down at a depth of 5 feet?
Assume (1) the cup has negligible weight, (2) the temperature of the air is always the same as the surrounding water temperature.
