1. Calculate the magnitude and direction of the electric field 2 m from a long wire that is charged uniformly with a linear charge density of A= 3.8.10-6 C/m. Hint: You can assume that the wire is infinitely long. If the wire is infinitely long, what happens to the components of the electric field in the plane perpendicular to the z-axis in the figure? Which components of the electric field survive and which don't? E= Vi+ P Z Z VkN/C X
