A spherically symmetric gravitational system of particles has a mass density \(\rho=\left\{\begin{array}{c}
\rho_{0} \text { for } r \leq R \\
0 \text { for } r>R
\end{array}\right.\) where ρ0 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 < ∞) from the centre of the system is represented by
