A finite line of charge with linear charge density λ = 3.80 × 10-6 C/m, and length L = 0.698 m is located along the x axis (from x = 0 to x = L). A point charge of q = -6.44 × 10-7 C is located at the point x0 = 1.14 m, y0 = 5.00 m. Find the electric field (magnitude and direction as measured from the x axis) at the point P which is located along the x axis at xP = 11.1 m. The Coulomb force constant k = 1/(4π ε0) = 8.99 × 109 N·m2/C2.
