E&M Problem - 2 Charged Masses Hanging on Strings

[QUOTE="inferno298, post: 4491831, member: 472354"] [b]E&M Problem -- 2 Charged Masses Hanging on Strings[/b] [h2]Homework Statement [/h2] Two charges of identical mass m, one with charge q, the other with charge 2q, hang from strings of length l from a common point. Assume q is sufficiently weak so that any angle you're looking for is very small, and find an approximate expression for the angle each charge makes with respect to the vertical. Check (and show) that the units work out, and that the limiting behavior for large mass, large length, and/or small q are at least sensible. [h2]Homework Equations[/h2] Coulombs Law [B]E[/B]=(1/4*pi*episolon)(q' [B]R[/B]/R) [h2]The Attempt at a Solution[/h2] First I am not sure what to do with the mass, if its really even needed. Also I am given lengths, but it doesn't specify that they are the vectors themselves, otherwise I would just use the r' vector to the charge and the r vector to some random point charge in the middle to grab the vertical angle. I think there is another way I am missing though. Any help or insight would be appreciated. [/QUOTE]
