1.let us suppose that a uniform, thin line of charge Q stretches from z=0 to z=L on theˆz-axis. This time calculate the electric field produced by the line at a point r=xˆx forx>0. This point is not equidistant from the two ends—does the electric field have both an x and a z component there?

2. A charge q is placed at the point r=xx^ for the electric field that you calculated in the previous problem.

a. What is the force on the charge?

b. Now evaluate the force in the limit that the charge q is 'far away' from the line, in the sense x>> L. What is the leading behavior of the x^ and z^ components? Do these answers (in particular the x^ component) make sense?

question 2 is more important for me
