The angles of one leave to the vertical vary from 22 to 36 degrees in my experiment, so the deflection is large. I am getting a trend proportional to the time my sphere was exposed to a Van der Graaff, so I need to somehow mathematically translate angle into charge or potential. I read in a...

So what I am looking for is a mathematical approach that doesn't assume the electroscope is made of two spheres, but something that (somehow) balances the forces in the whole leave and assuming both leaves are the same mass length and material, and knowing those properties plus the angle they...

The best idea I have now is to take the end of the leave and assume that all the mass of the leave is there, as if the electroscope was made of two hanging spheres instead of 2 leaves. Then I could balance mg, tension and electrostatic repulsión using the angle, get the charge in one sphere...

Yeah, I am sorry for the misleading post. I do not want to measure the potential between the leaves, but between the electroscope as a whole and a non charged reference. Want I really want to know is the charge/potential of the original sphere (in a sphere those 2 quantities are easily...

I am trying to measure the charge(or voltage) of a positively charged sphere by touching it with a non- calibrated electroscope. I am getting consistent results in the separation(or angle) between the metal leaves, but I don´t know how to calculate the voltage between the leaves from there. I...
