The resistance is defined in terms of the fluid viscosity and the sphere's velocity as follows:
Stokes explicitly calculated the resistance experienced by the sphere and determined that viscosity is proportional to the sphere's radius and its velocity, leading to the following equation for resistance:
A charged particle
This force is opposed by a force due to the effect of the medium that can be modeled by Stokes law
If both forces are equalized, it is obtained that the particle moves with a constant speed equal to
with mobility equal to
To equalize the force caused by the electric field
with the opposing force that is modeled with Stokes law
the relationship is obtained
with mobility equal to
