    Electric field inside a conductor

    While the glued charge stick is well depicting the situation I had in mind, I don't think the law E=0 for electrostatics actually contemplates such situations where the structure of a conductor is this dramatically altered. For instance I could glue not just a single charge but an amount so...

    Electric field inside a conductor

    Ok I guess this makes a good intuitive explanation of the QM phenomenon initially pointed out by mfb, thank you. I think one should have this idea clear in mind before studying electromagnetism, to understand that point charges are just an approximation. So for instance, how do you apply...

    Electric field inside a conductor

    That's exactly the reason why I'm asking this. I agree a situation like the one I described is confined to an ideal world, but Physics, as I understand it (as it is explained in textbooks), is developed around such ideal scenarios, so I was expecting this particular one to be somehow included...

    Electric field inside a conductor

    Indeed, before studying quantum mechanics I'm reviewing the contents of classical mechanics, so my question is related to it. I don't get this, does it mean in QM there are no point-charges? Ok, it's unstable and unlikely but not impossible, disregarding for a moment QM. Right now I'm studying...

    Electric field inside a conductor

    Suppose there is a metal disk with an initial excess of charge represented by the four red electrons. Naturally, they reach their equilibrium position on the surface. After this, a new electron (the green one) is added exactly at the center. The repelling forces from the red charges cancel each...
