2 A US Navy nuclear submarine (mass m = 10,000,000 kg) is cruising under the Arctic ice sheet at a depth of 200 m. (a) If the submarine is maintaining constant depth while cruising, what is the size of the buoyant force on it? (b) Assuming that the density of seawater is 1023 kg/m3, what is the volume of the submarine? (c) What is the water pressure at the cruising depth of the submarine (remember that the pressure increase due to the depth has to be added to the pressure at the surface, which is the atmospheric pressure PATM = 101,000 Pa)? (d) This submarine is fitted with a circular window of area A = 0.1 m2. Find the net force on this window (i.e., force from outside minus force from the inside) assuming that the air pressure inside the submarine is equal to PATM.
