A line of charge 2.0 m long has 50.0 nC of charge uniformly distributed along it. (a) Calculate the electric field 0.25 m above the center of the line. (b) If the field point were moved from 0.25 m to 1.0 m, by what factor does the field increase/decrease? (c) How does this compare with moving the field point from 0.25 m to 1.0 m away from a point charge?
