A straight line segment of length 2L carries a positive linear charge density of +1 on the x- axis from x = -L to x = 0, and a negative linear charge density of - 1 on the x- axis from x = 0 to x = L as shown below. a) What is the electric field a distance y above the midpoint of the line? Your answer should be in terms of the variables given and fundamental constants (i.e. A , L, y, k) b) Considering the limits of your expression, do you think the electric field from this line will decrease more slowly, more quickly, or the same as that of a point monopole? Please provide some reasoning to support your answer.
