In electrostatics, why the electric field inside a conductor is zero?
In electrostatics free charges in a good conductor reside only on the surface. There are at least two ways to understand this So the free charge inside the conductor is zero. So the field in it is caused by charges on the surface. Since charges are of the same nature

Lecture Notes Chapter 1
A neutral atom, placed in an external electric field, will experience no net force. However, even though the atom as a whole is neutral, the positive charge is concentrated in the nucleus (radius = 10-14 m) while the negative charge forms an electron cloud (radius = 10-10 m) surrounding the nucleus (see Figure 4.1). The nucleus of the atom will experience a …
