Two identical balls of mass 38 g are suspended from threads of length 1.5 m and carry equal charges of 16 nC as shown in the figure. Assume that θ is so small that its tangent can be replaced by its sine and find the value of x.(adsbygoogle = window.adsbygoogle || []).push({});

(picture attached)

I know that the sum of all the forces must equal zero.

Fy: Tcosθ-mg=0

Fx: Tsinθ-[(k*q^2)/(x^2)]=0

Are these correct? I'm also confused on where to go from here.
