The pressure inside a commercial airliner is maintained at 1.00 atm (10⁵ Pa). What is the net outward force exerted on a 1.0 m * 2.0 m cabin door if the outside pressure is 0.40 atm?

Question

The net outward force is calculated by finding the difference in pressure inside and outside the cabin and multiplying by the area of the door. The pressure difference is (1.00 atm - 0.40 atm) = 0.60 atm = 0.60 x 10^5 Pa. The area of the door is 1.0 m x 2.0 m = 2.0 m². Therefore, the force is 0.60 x 10^5 Pa x 2.0 m² = 120,000 N.
