Dear student
The terminal velocity acquired by the ball of radius $r$ when dropped through a liquid of viscosity $\eta$ and density $\rho$ is, $v=\dfrac{2{{r}^{2}}\left( {{\rho }_{o}}-\rho \right)g}{9\eta }$. Note:Terminal velocity is defined as the maximum velocity attained by a body as it falls through a fluid.
thanks
