Are there (or could there be) electrically charged particles that move at the speed $c$? [duplicate]
A photon, a neutrino (if it has zero rest mass) move at $c$ but what about charged particles? If the answer is no, is there a fundamental reason or just because of the radiation it emits?

What would happen if a charge could travel at $c$? [duplicate]
We know that an electron can move at sublight speed, but can we figure out what would happen if a charge moved at $c$, surfing the wave of the electric field it has produced? There does not seem to be ...

A fundamental question about charge and speed of a particle [duplicate]
Hi everybody and happy 2019. In my teaching sessions sometimes someone asks questions i cannot truly answer (although i have many arguments on it) and here's one that really puzzles me:
A massless (...

Is it possible for a massless particle to have a charge? [duplicate]
I don't believe there is a massless charged particle, but would it even be possible for a massless particle to be charged as the energy of the charge itself would be a kind of non-momentum energy and ...

Can a massless charged particles moving with the speed of light exist? [duplicate]
Consider a massless charged particle uniformly moving in vacuum at a constant velocity with the speed of light. The usual expressions for electric and magnetic fields give weird results in this case. ...

Is charge without mass possible? [duplicate]
The minimum amount of charge possible is that of quarks. But it also has mass. Why is there no charge without mass? Or is it there?

Can a massless object have a charge associated with it? [duplicate]
So I've been stuck with this thought for a few days and have not been able to find an answer which can clear this doubt.
Is it necessary for an object to have certain mass associated with it if it ...

Can a mass-less charged particle exist? [duplicate]
According to known discoveries made till now , we have came across all the charged particles which have the property of mass . So can we assume that there is a correlation between charge and mass and ...

What would be the implications of finding a massless particle capable of carrying electric charge? [duplicate]
I came up with this question after discussing with a colleague (we're not physicists) about whether there existed a way of transferring electric charge without transferring mass. My question might be ...

Why do electrically charged fields necessarily interact with Higgs field? [duplicate]
There are no elementary charged particles without mass. Since elementary particles appear to acquire mass by the Higgs mechanism, the above statement seems to imply that any charged particle must ...

Is this proof that massless objects cannot be charged?
In the realm of pre relativistic physics.
$$\vec{p}=m\vec{v}$$
$$F= \frac{dp}{dt}= m\vec{a}$$
If there exists an electric field in space, the force experienced by it would be $$F= q\vec{E}$$
Applying ...

Why are there no elementary charged, spin-zero particles?
In the spirit of a related inquiry, I would like to know if there's a basis for understanding why there aren't any elementary particles that have non-zero electric charge but zero spin?
Can such a ...

Do particles with exactly zero energy exist?
In my understanding, in Newtonian mechanics if something has no mass it cannot be said to "exist" since it cannot possibly have energy or momentum and thus cannot participate in interactions or be ...
