A person rides up a lift to a mountain top, but the person’s ears fail to “pop”; that is the pressure of the inner ear does not equalize with the outside atmosphere. The radius of each eardrum is 0.397 cm. The pressure of the atmosphere drops from 1.008 × 105 Pa at the bottom of the lift to 98100 Pa at the top.

Answer in units of Pa.

2. What is the magnitude of the net force on each eardrum?
