Phys222 Lab Activity 3: Electric Fields for Continuous Charge Distributions Problem 2: A non-conducting rod has length 2/. The left half of the rod has a negative uniform linear charge density -Ao, and the right half has a positive uniform linear charge density + 20 (Zo is a positive constant). a. Find the electric field at point P (located a distance d from the rod). b. Suppose the rod is now turned into an infinitely long rod (with two semi-infinite halves) with the same linear charge density as before. What would the electric field be at point P? y P X L L
