As we learn

 

 

 

- wherein

\eta = \frac{2}{9}\left (\rho -\sigma \right )g\frac{r^{2}}{v}

\eta = coefficient of viscoscity

\rho = density of ball

\sigma = density of liquid

r= radius of ball

v= terminal velocity of ball

F= 6\: \pi \: \eta\: r\: v

\Rightarrow F\alpha \: \eta

          \alpha \: r

           \alpha \: v
