- Find Millikan oil drop velocity

- Relevant Equations
- ##m\frac{dv}{dt} = \frac{4\pi a^3(\rho - \rho_1)g}{3} - 6\pi n a v##

Hi,

I try to find the velocity for a oil drop.

I found the forces.

##F=ma => m\frac{dv}{dt} = \frac{4\pi a^3(\rho - \rho_1)g}{3} - 6\pi n a v##

with v on the right side, I don't see how to get the solution.

I found the solution on few websites, but without the path to find the solution from the equation above.

This is basically, the Millikan oil drop experiment without the electric field.
