A spherically symmetric gravitational systom of particles has mass density $ρ = \left\{$ $\begin{array}{ll}{ρ}_{0}\text{for}r \le R \\ 0\text{for}r > R\end{array}$ $\right) where,$ {ρ}_{0} $is a constant. A test mass can undergo circular motion under the influence of the gravitational field of particles. Its speed$ v $as a function of distance$ r ( 0 < r < \infty )$ from the centre of the system is represented by
