The surface area of the window of an airplane cockpit is 3m . At one point during a flight, the window experiences a net force pushing out of N. If the cockpit is pressurized at 1 atm, what is the air pressure outside the airplane?
Since there is a net force pushing out, the air pressure outside the airplane is less than that inside. Using equation (2) to convert the pressure to SI units and equation (1) to solve for the outside pressure yields:
