Understanding the Net Force on a Snorkeler's Eardrum

Click For Summary
SUMMARY

The discussion centers on the net force acting on a snorkeler's eardrum, specifically addressing the forces due to pressure differences. It confirms that the force on the eardrum arises from both the internal pressure within the ear and the external pressure from the surrounding water. The correct approach involves calculating the net force by considering both pressures, which is essential for understanding the physical dynamics experienced by snorkelers.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Knowledge of pressure concepts in physics
  • Familiarity with the anatomy of the human ear
  • Basic grasp of force calculations
NEXT STEPS
  • Research the effects of hydrostatic pressure on human physiology
  • Study the principles of buoyancy and its impact on underwater activities
  • Explore the relationship between pressure and volume in gases using Boyle's Law
  • Learn about the mechanics of sound transmission in fluids
USEFUL FOR

Physicists, diving instructors, medical professionals, and anyone interested in the effects of pressure on human anatomy while snorkeling or diving.

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
Relevant Equations
P=F/A
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?
