Question

Which of the following statements about a metal wire in equilibrium are true? Select all that apply O There may be excess charges on the surface of the wire. The interior of the metal wire is neutral. There are no excess charges in the interior of the wire. OThere is no net flow of mobile electrons inside the wire. There may be a constant flow of mobile electrons inside the wire. The net electric field everywhere inside the wire is zero. The electric field inside the wire may be nonzero but uniform. There may be excess charges in the interior of the wire. There cannot be excess charges on the surface of the wire.

Explanation / Answer

True Statements are :

1) -   The interior of the metal wire is neutral - as the total number of positive charge is equal to the total number of negative charge inside the wire.

2) - There may be excess charge on the surface of wire - inside the wire total charge is zero but as its, a metal means there are free electrons which reside on the surface of the wire which moves as charge carriers when the electric field is applied.

3) - There are no excess charge on the interior of wire - mentioned in point 2 all the extra charge lies on the surface making interior neutral.

4) - There is no net flow on mobile electrons inside the wire - if there were flow then it will be due to the excess electrons but there are none because of the neutrality.

5) - The net electric field everywhere inside the wire is zero - because the total charge is zero which makes electric field zero.
