Does air pressure act the same on all objects? Imagine you have two pistons, each with a 100PSI of air acting on one side of them. One piston is a cylinder, naturally. The other piston is a cone shape. Do both pistons have the same amount of force pushing them to the right (see; picture)? Or does the cone have less force pushing it to the right because it also has some force pushing it up, down, diaganol etc etc because of the cone shape? Thanks.
