If I have a charged particle floating in a vacuum, and it strikes a conductor or insulator on its way, what would happen? Would the electron be taken into the conductor? or would it just bounce off the surface. What about the insulator and why? And I think the particles kinetic energy does play a role in this. Thanks.
EDIT: In this question, by floating, I meant that the charged particle is not bound by any nucleus and has no other forces acting on it except for the force due to the conductor or Insulator.
and what I personally thought was that when the charged particle hits the conductor, it will get absorbed because of the induced negative charge, but for the Insulator, I don't what will happen. I am thinking since charges are almost immobile in an insulator, It won't be able to accept the charged particle unless it is of the opposite charge of the particle itself. So, maybe in all other cases, it would result in some sort of bouncing off effect. I don't know how, though. But when the particle has high enough energy, particle physics might play a role. This is where I need help and at what energies does particle physics come into play?
