A thin, long rod of length 13.0 m lies along the x axis with its center at the origin. The total charge on the rod is -270 c. "P(O)) 1/2 (a) What is the net electric field at the location (0, 45.5 m)? (Express your answer in vector form.) Erod X Consider the electric field due to a small element of the rod. By symmetry, what happens to the x components of the field? Review rules of integration. N/C (b) To see how the value of the electric field changes if y >> L, determine the net electric field at the location (0, 455 m). (Express your answer in vector form.) rod N/C A large sheet of charge has a uniform charge density of 59 pc/m. What is the electric field (in N/C) due to this charge at a point just above the surface of the sheet? (Enter the magnitude.) N/C Additional Materials Reading
