The exact analytical Wyman-Adler’s relativistic solution describing the interior of a charged spherical strange star candidate is found under the assumption and existence of two parameters K and m. The interior self-bound star matter, pressure, energy density and the adiabatic sound speed are represented in terms of simple algebraic function. The analytic solution depicts a unique static charged configuration of quark matter with radius R~9 km and total mass M~2.5M¬¬⊙. And try to investigate the velocity of sound approximately 1/√3 which is similar to the attitude of SQM (Strange Quark matter). Based on analytic model in the recent work, the applicable values of physical quantities have been calculated by accepting the estimated masses and radii of some well-known strange star candidates like PSR J1903+327, Her X-1, Cen X-3, EXO 1785-248. The equation of state of the charge matter distribution may play a major role in the study of the interior structure of highly compact charge stellar object in astrophysical study.
