  New exact solutions of Einstein's field equations for charged stellar models
by assuming linear equation of state $ P_r=A(\rho-\rho_{a}) $, where $ P_r $ is
the radial pressure and $ \rho_{a} $ is the surface density. By assuming $
e^{\lambda} = 1+\frac{r^2}{R^2} $ for metric potential. The physical
acceptability conditions of the model are investigated, and the model is
compatible with several compact star candidates like 4U 1820-30, PSR J1903+327,
EXO 1785-248, Vela X-1, PSR J1614-2230, Cen X-3. A noteworthy feature of the
model is that it satisfies all the conditions needed for a physically
acceptable model.
