In empty space there is (-∞, 0) semi-infinite linear uniform and constant charge density ρ_l = 4 [C / m] on the z-axis. Calculate the electrostatic field that this charge density will create at point A (5,0,0). k_e = 1 / 4πε
Write numerically the components of the electrostatic field in terms of the given quantities.
