Thank you all so much, I thought I was going crazy cause I couldn't figure out how to do it without mass. So is there no way to derive the mass either since density of the pith ball is not known, meaning the problem did not give enough information?
I tried going about solving it without having mass in my equations but I always ended up having to find it to get Q. If there is a way to solve it without knowing the mass than I've never been taught it. If you do know a way to do it without mass could you provide some hints/guidance?
I actually found most of it out I'm just struggling with how to find the mass of the balls. I'm not sure how you would do that since could only derive two equations from the information given or are we assuming the mass is so small that it doesn't matter?
Q = charge of one pith ball
d =...
