Question
Pr5. Two hemispherical shells of negligible mass and radius R= 1.2 m are put together along
their horizontal rim, then the (now complete) sphere is submerged in water. The lower hemisphere
is tied to the bottom of the water tank, and this way the center of the sphere is located at depth
H = 10 m. Inside the sphere there is air of pressure po = 105 Pa (which is the same as the
atmospheric pressure). Find the force exerted by the lower hemisphere on the upper hemisphere.
