A total of 3.04 106 electrons are placed on an initially uncharged wire of length 1.23 m.
(a) What is the magnitude of the electric field a perpendicular distance of 0.360 m away from the midpoint of the wire?
(b) What is the magnitude of the acceleration of a proton placed at that point in space?
(c) In which direction does the electric field force point in this case?
