If the bottom of a pop bottle similar to that shown in Video V2.5 were changed so that it was hemispherical, as in Fig. P2.70, what would be the magnitude, line of action, and direction of the resultant force acting on the hemispherical bottom? The air pressure in the top of the bottle is 40 psi, and the pop has approximately the same specific gravity as that of water. Assume that the volume of pop remains at 2 liters.
