My bad, I assumed that people would know.
E = kQ/r
where k is the constant of 9.0E9, Q is the charge of the point charge, and r is the distance from the point charge.
For two point charges of the same charge (positive) that are placed a distance from each other "r", the electric field in the midpoint of r is zero.
Now here's my question, what if one point charge had double the charge of the other? At what point between the two charges the electric field...
I have no clue. I'm just multiplying F with T^2.
I've done some research to help myself, though I still don't know what's going on. Here's the link I found, scroll down to the bottom for the tidbit on FT^2.

I need help with this lab I'm doing involving swinging a mass in a circle (I'm sure you guys have heard of it). I have to plot a graph of Radius vs. FT^2 and then compare the value of the slope to its theoretical value.
A couple questions:
Which goes on the y axis? Radius or FT^2?
How do I...
