SUMMARY

The discussion centers on calculating the distance between two charged particles, an electron and a proton, released simultaneously from parallel copper plates separated by 0.05 meters in a uniform electric field. The key factor affecting their paths is the significant mass difference, resulting in different accelerations. The electron, being much lighter, will travel faster than the proton, leading to a non-equidistant crossing point. Understanding the net forces acting on each particle is crucial for solving this problem.

PREREQUISITES
  • Understanding of electric fields and forces
  • Basic knowledge of Newton's second law of motion
  • Familiarity with particle mass and acceleration concepts
  • Ability to apply kinematic equations for motion
NEXT STEPS
  • Study the concept of electric field strength and its effects on charged particles
  • Learn how to calculate the net force acting on charged particles in an electric field
  • Explore kinematic equations to determine the motion of particles under constant acceleration
  • Investigate the mass-energy relationship and its implications in particle dynamics
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the dynamics of charged particles in electric fields.

Two large parallel copper plates are .05 meters apart and have a uniform electric field between them. An electron is released from the negative plate at the same time that a proton is released fro the positive plate. Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other.

I am seriously absolutely lost with this and don't even have a clue where to start.

Thanks for any help!

In the uniform electric field, both will experience a force and thus an acceleration. The hitch which makes them not cross at an equidistant location is that the proton is much more massive than the electron.

Without any attempt from you, I can't help you so very much, but I would start at looking at the net force on each; hopefully this points you in the right direction.
