A small ball of mass M and density \rho is dropped in a viscous liquid of density \rho_0. After some time, the ball falls with a constant velocity. What is the viscous force on the ball?

Correct Answer is : F=Mg(1−ρ0ρ)

{\F}= {\Mg} (1-\frac{\rho_0}{\rho})

{\F}= {\Mg} (1+\frac{\rho}{\rho_0})

{\F}= {\Mg} (1+\frac{\rho_0}{\rho})

{\F}= {\Mg} (1 \pm \rho \rho_0)
