A thin rod lies along the positive r-axis and has uniform linear charge density A = +6.0 x 10-15 C/m. Its left end is located at , = +2.0 m, and its right end extends out to infinity. An electron is placed at the origin and released from rest. Determine the electron's acceleration immediately after being released. (Hint: this will require building and evaluating an integral.) In your diagram, make sure to pick out an arbitrary element of charge along the rod, and indicate the force it exerts on the electron. For your limit check, investigate what happens to the electron's initial acceleration as the left end of the rod is moved closer to the origin (i.e., as z, 0)
