Possible variables for Coulombs Law?

AI Thread Summary
Coulomb's Law is expressed as F = K Q1 Q2 / R^2, but solving for both Q1 and Q2 requires additional information since there are two unknowns. The discussion highlights that one cannot isolate two variables with a single equation. If values for F, K, Q1, and R are known, Q2 can be calculated using the rearranged formula Q2 = (F R^2) / (K Q1). The conversation emphasizes the necessity of having more data to solve for both charges independently. Understanding these variables is crucial for applying Coulomb's Law effectively.

COULOMBS LAW
F= K Q1 Q2 / R2

How would I solve for Q1 and Q2?

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 }##

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
