A charged rod of total length 3.7 m lies centered on the x axis as shown (the L indicated in the picture is half of that number, meaning that L = 1.85 m). The rod has a charge density which varies according to λ=ax2 where a=−87.3 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=8.1 m from the end of the rod? Use a negative sign for a field pointing in the -x direction.
