Finding the Electric Field Between Charges [picture]

Click For Summary

Homework Help Overview

The discussion revolves around determining the region along the line connecting two charges where the electric field is zero. The charges are identified as both being positive, leading to a repulsive interaction.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the location of the point of zero electric field, with initial thoughts suggesting it might be in the middle of the charges. There is a correction regarding the nature of the charges, emphasizing their repulsive force.

Discussion Status

The discussion is ongoing, with participants clarifying the nature of the charges and questioning the initial assumptions about the electric field's behavior. A resource link has been provided for further exploration of the topic.

Contextual Notes

There is a mention of a correction regarding the charge values, indicating that one charge is negative, which may affect the analysis of the electric field's behavior.

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.
