#### Full Text

In this paper we have obtained some exact static spherical solution of Einstein’s field equation with cosmological constant $\wedge=0$ and equation of state $p=\rho$ (taking suitable choice of $g_{11}$ and $g_{44}$). We have taken $e^{\beta}=lr^{n}, e^{\beta}=lr^{n-1}, ~\text{and}~ e^{\beta}=lr^{7/5}$ (where $l$ is a constant), which help to investigate the value of $e^{\alpha}$. Many previously known solutions are contained here in as a particular case. Various physical and geometrical properties have been studied.
