Consider the window $($of area $0\mathrm{.}9$ m$2)$ of an airplane. If the pressure inside the plane is atmospheric pressure, while the pressure outside is $22\%$ of Patm, find the magnitude of the force on the window. Ignore the velocity of the airplane $($i$.$e$.,$ ignore Bernoulli$$s effect$).$

Is the force directed towards the inside of the airplane or towards the outside of the airplane?

$$Impossible to tell which way the force points.

$$Towards the inside of the airplane.

$$Towards the outside of the airplane
