Positive charge Q is distributed uniformly along the x-axis from x = 0 to x = a. A positive
point charge q is located on the positive x-axis at x = a +r, i.e., a distance r to the right of the
end of Q (see figure below).
(a) Calculate the x- and y-components of the electric field produced by the charge distribution
Q at points on the positive x-axis where x > a. Express in terms of Q,r, a.
(b) Calculate the force that the charge distribution Q exerts on q. Express the force in terms of
the standard unit vectors î and ĵ, and the symbols Q,r, a.
