In the figure, short sections of two very long parallel lines of charge are shown, fixed in place, separated by L = 100 cm. The uniform linear charge densities are +9.12 μC/m for line 1 and −2.33 μC/m for line 2 . Find the magnitude of the electric field at x = 0. Enter a positive number for an electric field that points to the right or a negative number for an electric field that points to the left. N/C
