Estimating Particle Number in an Electric Field

[naviakam]

TL;DR

In an electric field how the ion numbers are calculated?

In an electric field $E$ if the energy of charged particle (ion) is formulated as $W=qEr$ where $r$ is the distance, how the number of particles is estimated?

 

[BvU]

There is no relationship between 'the number of particles' and anything else you write. Or is there ?
