SUMMARY

The discussion centers on calculating the distance of closest approach for two protons moving towards each other at initial speeds of 3.00 x 10^6 m/s. The key points include the understanding that both protons will momentarily come to rest at their closest approach due to their identical speeds. At this point, their kinetic energy is converted into potential energy, which is crucial for determining the distance of closest approach using principles of energy conservation.

PREREQUISITES
  • Understanding of kinetic and potential energy concepts in physics
  • Familiarity with the principles of energy conservation
  • Basic knowledge of electrostatic forces between charged particles
  • Ability to apply Newton's laws of motion
NEXT STEPS
  • Study the conservation of energy in particle interactions
  • Learn about electrostatic potential energy between charged particles
  • Explore the concept of distance of closest approach in particle physics
  • Review Newton's laws of motion and their applications in collision scenarios
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding particle interactions and energy conservation principles in the context of charged particles.

Homework Statement


Two protons are moving directly toward one another. When they are very far apart, their initial speeds are 3.00*10^6 m/s. What is the distance of closest approach?


Homework Equations





The Attempt at a Solution


I really need help in question. I need to know how to start this question. Please help! Thank you!

They both have kinetic energy.

If they have identical speeds, then they will both momentarily come to rest at their closest approach.

If they are at rest relative to each other then what is their potential energy with respect to each other at that moment?
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
