Homework Statement: What is the net force on the ocean snorkeler of Question 1 if the pressure inside her ear is 1.0 atm (=101.3 kPa)? An adult's eardrum has a typical diameter of 8.0 mm

Can someone help me understand what I did wrong when solving this problem?

You found the force on the eardrum due to the pressure inside the ear. Is there also a force due to pressure outside the ear?
