We prove \(L^p\) lower bounds for Coulomb energy for radially
symmetric functions in \(\dot{H}^s(\mathbb{R}^3)\) with \(1/2 <s<
3/2\). By this bound we can improve sobolev embedding for radial
functions in \(\dot{H}^s(\mathbb{R}^3)\) with bounded Coulomb
energy. This result is sharp for \(1/2<s<1\).
