Finding the Electric Field Between Charges [picture]

Click For Summary
SUMMARY

The discussion centers on determining the location of a point of zero electric field between two positive charges. The user initially misinterpreted the nature of the charges as attractive but later corrected this to recognize that both charges are repulsive. The user also referenced a specific educational resource from MIT's OpenCourseWare, particularly Lecture 2 on electric fields and dipoles, which provides valuable insights into this topic.

PREREQUISITES
  • Understanding of electric charge concepts, specifically positive and negative charges.
  • Familiarity with electric field theory and its implications for charge interactions.
  • Basic knowledge of vector addition as it applies to electric fields.
  • Access to educational resources on electricity and magnetism, such as MIT OpenCourseWare.
NEXT STEPS
  • Review the MIT OpenCourseWare Lecture 2 on electric fields and dipoles for a deeper understanding.
  • Study the concept of electric field lines and their behavior between different charge configurations.
  • Learn about the superposition principle in electric fields to analyze multiple charge systems.
  • Explore the mathematical formulation of electric fields due to point charges, including the use of Coulomb's Law.
USEFUL FOR

Students studying physics, educators teaching electricity and magnetism, and anyone interested in understanding electric field interactions between charges.

Homework Statement



5. There are two charges in space. In which region of the line connecting these two
charges can we find a point of zero electric field?


Homework Equations



None.

The Attempt at a Solution



I know this isn't even that hard. I was thinking it was somewhere in the middle because the charges are attractive but this is not so.

The charges aren't attractive, they both are positive. They are repulsive
 
Yikes I drew that picture incorrectly! That should read negative 5C. I'm redoing it now.
