Question

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 ?

Select the correct option:

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

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

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

$\mathrm{F}=\mathrm{Mg}\left(1 \pm \rho_0\right)$

✓ Correct! Well done.
