Two solid spheres ( A and B ) are made of metals of different densities \rho_A and \rho_B respectively. If their masses are equal, the ratio of their moments of inertia (I_B \/ I_A) about their respective diameter is

Correct Answer is : (ρAρB)2∕3

(\frac{\rho_B}{\rho_A}) ^{2 \/ 3}

(\frac{\rho_A}{\rho_B}) ^{2 \/ 3}
