Solutions of unified theory equations of gravity and electromagnetism satisfy Einstein-Maxwell equation. Hence, solutions of the unified theory is Reissner-Nordstrom solution in vacuum. We found in revised Einstein gravity tensor equation, the condition is satisfied by 2-order contravariant metric tensor two times product and Gauss symbol.
