Homework Help Overview

The discussion revolves around the relationship between the elementary charge squared and Coulomb's constant, specifically questioning whether the product equals one. Participants are exploring the context of this relationship within the framework of electrostatics.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants express uncertainty about the correct approach to the problem and question the values being used. Others seek clarification on the definition of Coulomb's constant and the elementary charge.

Discussion Status

The discussion is ongoing, with participants providing definitions and questioning assumptions. There is an acknowledgment that the initial premise may not hold true, but no consensus has been reached on the implications of this realization.

Contextual Notes

Participants mention potential confusion regarding the units and whether to use atomic units (au) in their calculations. There is also a reference to the specific value of Coulomb's constant and the elementary charge, which may influence the calculations being discussed.

I'm not really sure how to go about this

Homework Equations



whenever I plug in the correct values I don't get 1. Unless I'm supposed to use au.

The Attempt at a Solution

Well what is Coulomb's constant?

Am I correct in assuming that e is the elementary charge?
 
it's 1/(4*pi*episolon naught) where episolon naught is 8.85 x 10^-12 F/m. yes, e is the elementary charge.

Then there is nothing left to do since as you have now pointed out in your edited opening post, it is clear that

e^2 \cdot\kappa \neq 1
