A small ball of mass $$m$$ and density $$\rho$$ is dropped in a viscous liquid of density $$\rho_0$$. After sometime, the ball falls with constant velocity. The viscous force on the ball is :

$$m g\left(1-\frac{\rho_0}{\rho}\right)$$

$$m g\left(\frac{\rho_0}{\rho}-1\right)$$

$$m g\left(1-\rho \rho_0\right)$$

$$m g\left(1+\frac{\rho}{\rho_0}\right)$$
