I think this thing came to my mind some times after I studied Electromagnetism when I studied Physics; otherwise, I would have asked it to my professor. (Incidentally, I'm still studying and I'm involved in Electromagnetism, but for a totally different course )
We know from Coulomb's Law that, if we have two charges, they attract or repel each other and the result is a force: (sorry, but writing formulas, even simple, is a pain in the... )
F=(k*q1*q2)/r²
While Newton's Second Law of Dynamics states that:
F=m*a
If we compare the members of the equations (sorry, I don't know if it's the right way to say that), we have:
a=(k*q1*q2)/(m*r²)
What struck me once and what I want to point out is:
we have an interaction between charges, but its result applies to masses. Why doesn't it apply to charges themselves? Why charge interaction is a force?
Let's suppose we have a particle with charge, but no mass: what would it happen then if it interacted with another particle of the same type? There would be an interaction, but it would apply to what?
(Ok, perhaps I know the answer: no particles with charge e no mass (for some very complex reason) can exist)
