In the higher-dimensional space-time, the metric coefficients g00 and g11 of both the Schwarzschild and Reissner-Nordstr?m metrics satify the relation g00g11 =-1. Byconsidering that rhe relation between the metric coefficients is valid inside a chargedperfect-fluid distribution, and assuming the mass density σ=σ0rbe-λ(r)/2, weobtain an exact interior solution far a static charged sphere in the higher-dimensional space-time.
