Saul ascends from the city of Tucson, Arizona to the top of Kitt Peak, 2900 m above the sea level. Usually, Saul will feel his ears “pop” as the pressure inside his ears attempts to maintain the equilibrium with the surrounding air. However, on this day Saul has cold and his Eustachian tube is clogged, causing a tremendous pressure behind his 4.0×10^(-5) m^2 ear drum. What force does Saul feel pushing on his ears? (D_air=1.20 kg/m^3
