Electric Field of Equilateral Triangle Charge Distribution

Click For Summary

Homework Help Overview

The discussion revolves around the electric field generated by three negatively charged spheres positioned at the vertices of an equilateral triangle. Participants are exploring the implications of charge distribution on electric field lines, including the behavior of a test charge in the vicinity of these charges.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to visualize the electric field by placing a positive test charge near the negatively charged spheres. There are discussions about the direction of electric field lines and the forces acting on a third charge placed between two other charges. Questions arise regarding the interpretation of signs in calculations and the resultant forces on charges.

Discussion Status

There is an ongoing examination of the calculations related to forces and electric fields, with some participants providing guidance on how to approach the signs of the forces and the directions of the electric fields. Multiple interpretations of the problem are being explored, particularly regarding the net forces and field strengths at specific points.

Contextual Notes

Participants are navigating through the complexities of charge interactions, including the need to define a consistent direction for positive and negative forces. There is a focus on ensuring clarity in calculations while adhering to the conventions of electric charge behavior.

But you have to choose the vector carefully.

Force exerted on charge at B by charge at A is in the direction of AB, and electrostatic field intensity E at B due to charge at A is in the direction AB.

So, if the charge at A is actually negative, putting in the actual negative value gives you an intensity in the direction of -AB, as should be the case.
