When the textbooks try to show why the electric field inside a conductor is zero they say let us put our conductor in an electric field What happens then is that there will be an induced surface charge density which consequently induces an electric field within the conductor such that the total electric field within the conductor will be zero...
So in this case, we said the electric field at this point is equal to-- and the units for electric field are newtons per coulomb, and that makes sense, right? Because it's force divided by charge, so newtons per coulomb So if we know that the electric charge-- well, let me put some real numbers here Let's say that this is-- I don't know...
