If a dense, spherical star were made of uniformly charged matter, there'd be an attractive gravitational force and a repulsive electrical force. These would balance for a very small net charge: d F = 1 r 2 ( − G M inside d m + 1 4 π ϵ 0 Q inside d q) which balances if. d q d m = Q inside M inside = G ⋅ 4 π ϵ 0 ...
