Possible variables for Coulombs Law?

Click For Summary

Homework Help Overview

The discussion revolves around Coulomb's Law, specifically the equation F = K Q1 Q2 / R², and the challenge of solving for the variables Q1 and Q2 given the presence of only one equation with two unknowns.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the implications of having one equation for two unknowns, questioning the feasibility of solving for both Q1 and Q2. Some express curiosity about manipulating the equation to isolate one variable while others emphasize the limitations of the scenario.

Discussion Status

The discussion is active, with participants questioning the ability to solve for two variables with a single equation. Some guidance has been offered regarding potential manipulations of the equation, although no consensus has been reached on a definitive approach.

Contextual Notes

Participants note the constraints of the problem, particularly the lack of sufficient equations to solve for multiple unknowns, and the specific variables that are known or assumed in the context of the discussion.

Hi, :welcome:

This really quantum physics ?

You have one equation for two unknowns ? Not enough !

I am not asking for a specific equation to be solved. I am asking if asked to solve for q1 and q2 how would I manipulate this equation?
 
You can not solve for two unknowns if you only have one equation.

How would I solve for q1 and q2 separately?
 
If you know ##F, k, q_1 ## and ##r## you solve for ##q_2## with ## q_2 = \displaystyle {F r^2 \over k q_1 }##
