Question

A glass bottle of soda is sealed by a screw cap. The absolute pressure of the carbon dioxide inside the bottle is 1.50 x10⁵ Pa. Assuming that the top and bottom surfaces of the cap each have an area of 4.10 x10^-4 m², get the magnitude of the force that the screw thread exerts on the cap in order to keep it on the bottle. The air pressure outside the bottle is one atmosphere.
