Field at End of Line of Charge A charged rod of total length 8.3 m lies centered on the x axis as shown (the L indicated in the picture is half of that number, meaning that L = 4.15 m). The rod has a charge density which varies according to λ = ax² where a = -50.8 μC/m³. -L TotalCharge What is the total charge on the rod? q = -2.42056496-10-3, Efield +L P X What is the component of the electric field at a point on the x axis a distance of D = 5.4 m from the end of the rod? Use a negative sign for a field pointing in the -x direction. eField = -2.2807856-105 N
