Finding the Distance Between Electrons in Equilibrium: What is the Solution?

Click For Summary
SUMMARY

The discussion centers on calculating the distance between two electrons in equilibrium, where the electric force exerted by one electron cancels the gravitational force acting on the other. The problem requires applying Coulomb's Law and Newton's Law of Universal Gravitation to establish the relationship between the forces. Participants emphasize the importance of presenting initial thoughts or attempts before seeking help, adhering to forum guidelines for effective collaboration.

PREREQUISITES
  • Coulomb's Law for electric force calculations

Homework Statement



An electron is released above the Earth's surface. A second electron directly below it exerts just enough of an electric force on the first electron to cancel the gravitational force on it. Find the distance between the two electrons.

Don't expect to receive any help until you show us something you've done.. or something you've thought about this problem and the way in which it COULD be solved in.
 
Welcome to PF John,

The forum rules require one to present one's own attempts or thoughts before asking for assistance. So, what have you attempted thus far?
