D. Sketch vectors at each of the marked points to represent the electric field E at that location. X Would the magnitude or the direction of the electric field x/ at point A change if: Rod . the charge on the rod were increased? Explain. X X A B X If the charge on the rod increased, the direction of X the vector would not change but the magnitude of the electric field would increase due to an increase in the charge of the rod. Top view . the magnitude of the test charge were increased? Explain. . the sign of the test charge were changed? Explain
