What would the slope of the force between 2 charged particles vs 1/r^2 give me?

AI Thread Summary
The discussion revolves around understanding the slope of a graph depicting the force between two charged particles as a function of distance, specifically in relation to the inverse square law (1/r^2). Participants seek clarification on what to plot on the y-axis and x-axis, along with their respective units. The gradient of the plot, defined as Δy/Δx, raises questions about how to determine the units for the slope in this context. Understanding these units is crucial for interpreting the physical significance of the slope. Clear definitions of the axes and their units are essential for accurate analysis.

Homework Statement
A lab was performed by taking 2 charged particles at varying distances and measuring the force between them. (Dry data, and a graph of Fe vs 1/r^2 have been given.) Assume the charges are equal of magnitude. using the slope of the line and the value of coulomb's constant constant, calculate for the charge on one particle
Relevant Equations
Fe=(kq1q2)/(r^2)
I can get the slope of the line, but then I dont know what the slope is (units or whatever it is) then i get lost from there.

What did you plot on the ##y## axis and in what units? What did you plot on the ##x## axis and in what units? If the gradient of a ##y##-versus-##x## plot is ##\Delta y/\Delta x## then can you determine the units in this case?

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...
