I Estimating Particle Number in an Electric Field

Click For Summary
The discussion centers on estimating the number of charged particles in an electric field, where the energy of an ion is expressed as W=qEr. Participants question the relationship between the energy equation and the number of particles present. Clarification is sought on whether the energy formulation can be used to derive the particle count. The conversation highlights the complexity of linking energy to particle number in this context. Ultimately, the relationship between the energy of charged particles and their quantity remains ambiguous.

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?

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

Thread 'The rocket equation, one more time'

I already posted a similar thread a while ago, but this time I want to focus exclusively on one single point that is still not clear to me. I just came across this problem again in Modern Classical Mechanics by Helliwell and Sahakian. Their setup is exactly identical to the one that Taylor uses in Classical Mechanics: a rocket has mass m and velocity v at time t. At time ##t+\Delta t## it has (according to the textbooks) velocity ##v + \Delta v## and mass ##m+\Delta m##. Why not ##m -...
