For that matter we consider three important scenarios where the equation of state parameter $\\omega_{q}$, has one of the following forms (i) $\\omega_q=-1$ (ii) $\\omega_q=-2/3$ and (iii) $\\omega_q= -1/3$. The existence of such marginally stable circular orbits in these scenarios depend on the range of normalization factor $\\alpha$. Briefly, we show that in the first case such orbits exist only if $0<\\alpha<4/16875$.
