Electrostatics Of Conductors

In electrostatics, it is a well-established fact that:
- Excess charge always resides on the surface of a conductor. This is because like charges repel each other, so they tend to spread out over the surface of the conductor.
- The electric field inside a conductor in electrostatic equilibrium is zero because the charges move to cancel out any internal fields.
- The electric field at the surface of a conductor is perpendicular to the surface (not tangential).

Thus, the correct statement is that any excess charge resides on the surface of the conductor.
