Why the velocity of electrons is zero in conductor at start due to electric field?

Question

Answer

In a conductor, say a metal wire, the charge carriers (electrons) are able to move under the influence of even a tiny electric field.

As the electrons are free to move they do so until they find positions where they feel no net force. When they come to rest the interior of the conductor must have zero electric field.

This means The net charge on a conductor only exists on the surface and electric fields inside the conductor is zero.
