In the figure, two tiny conducting balls of identical mass m and identical charge q hang from nonconducting threads of length L. Assume that q is so small that tanq can be replaced by its approximate equal, sinq.(adsbygoogle = window.adsbygoogle || []).push({});

First find an expression for x in terms of L, q, m, k and g.

Then, given L = 100 cm, m = 7.00 g, and x = 3.00 cm, use the expresion above to calculate the magnitude of q: ((1.02e-8 C)) << correct answer

so i started with sumF=ma= kq^2/x^2 + Xcomp of the Tension.

I think i'm screwing up because i don't remember how tension works as a force.
