The discussion revolves around estimating the total excess charge on a conducting sphere charged to a potential of 2,000,000V in the context of a Coulomb Balance experiment. Participants are exploring the relevant equations and concepts related to this scenario.
Some participants have suggested potential equations, such as V = q/R and C = 4∏ε0r, while noting the importance of knowing the radius. The discussion is ongoing, with various interpretations and approaches being explored.
There is an emphasis on the need for specific values, such as the radius of the sphere, to apply the formulas correctly. The choice of geometry in the experiment is also under consideration.

If conducting a Coulomb Balance experiment, and a question asks to estimate the total excess charge on a sphere with a conducting surface charged to 2,000,000V potential.
Is there a specific equation I should be using to estimate this?
Thank you.
P.S. why are spheres used in such an experiment, and not some other shape?

(Sorry for large font, I was trying to obtain a small 0 beside ε!)
