A charged rod of total length 4.4 m lies centered on the x axis as shown (the L indicated in the picture is half of that number, meaning that L = 2.2 m). The rod has a charge density which varies according to λ=ax2 where a=−32.5 μC/m3. What is the total charge on the rod? What is the x component of the electric field at a point on the x axis a distance of D=3.5 m from the end of the rod? Use a negative sign for a field pointing in the -x direction.
