Conceptual E&M question

Hello.

I know that for a particle in motion, (let's say a point charge), the electric field generated is given by the Lienard-Wiechert potentials.

My problem is as follows. Let's say I have a point charge in motion, and I wanted it to come to rest so that it remains stationary. Would I just set up an Electric field equal and opposite to the E-field given by the Lienard-Wiechert potentials?

If someone could explain how I would be able to bring the point charge in motion to rest, I'd appreciate it.

Thanks.

Hello and thank you for posting your question to Barinmass.

We assume a point charge moving at constant speed.

One of the basic postulates of E&M is that the fields (or potentials) generated by a charge do not have any effect on the generating charge itself.

Why go to Maxwell equations (which are the source of the LW ...
