A high-pressure industrial container is filled with nitrogen gas. It features two horizontal relief plates, Plate A and Plate B, located on its upper surface. The surface area of Plate A is 0.15 m2 and the surface area of Plate B is 0.45 m2.
Explain, with reference to pressure, how the force exerted by the nitrogen gas on Plate B compares to the force exerted on Plate A.
