Answer to Question #258704 in Physics for P.I

Question

Estimate the net force exerted on your eardrum due to the water above when you are

swimming at the bottom of a pool that is 5.0 m deep. The pressure inside the eardrum is

atmospheric. [5N, Because a force on the eardrum of this magnitude is uncomfortable,

swimmers often “pop their ears” by swallowing or expanding their jaws while underwater, an

action that pushes air from the lungs into the middle ear. Using this technique equalizes the

pressure on the two sides of the eardrum and relieves the discomfort
