E-field Lines

Why the field lines are always perpendicular to the conducting line?
 
Think about the structure of a conductor. An electric field line that is not perpendicular to a conducting plane will have a component parallel to it. This electric field then acts on the electrons in the conductor and they will re-arrange themselves so that there is no longer any force acting on them (i.e. the field lines are perpendicular to the conductor)
 
thank you so much
