Homework Help Overview

The discussion revolves around the nature of electric charges, specifically the attraction of unlike charges and the repulsion of like charges. Participants are exploring the relationship between these phenomena and Newton's Third Law of Motion.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning whether the attraction of unlike charges and the repulsion of like charges can be explained through Newton's Third Law. There is a discussion about the reality of the forces involved, with some questioning if the repelling force is a real force or a fictitious one.

Discussion Status

Some participants have provided insights regarding the nature of the Coulomb force, asserting it as a real force. However, there is still uncertainty regarding its relation to Newton's Third Law, with no explicit consensus reached on the matter.

Contextual Notes

Participants express a desire to clarify these concepts without direct input from their lecturer, indicating a potential gap in understanding related to fundamental physics principles.

Unlike charges attract. Now here is my question, is this a phenomenon of Newton's third Law? I couldn't ask my lecturer because I had to run to another class for a quiz. It's friday and I don't want to ruin his friday.

The "repelling" force is a real right?

The "repelling" force is a real right?

The application of N3L in this case would be the idea that both charges experience an equal force in antiparallel directions; it doesn't really comment on WHY opposite charges attract and like charges repel.
 
But the repel must have a force right? Or is it one of those "fictitious forces"?
 
Am I right though?
 
The Coulomb force (attracting or repelling) is a real force.
 
But it is under Newton's Third Law?
