11. In Fig. 11, two tiny conducting balls of identical mass m and identical charge q hang from nonconducting threads of length L. Assume that θ is small, then the equilibrium separation x is approximately (A)q²L/(4πε₀mg) (B)[q²L/(4πε₀mg)]1/2 (C)2[q²L/(4πε₀mg)]1/2(D)[q²L/(2πε₀mg)]1/3 (E)3[q²L/(πε₀mg)]1/3
