A. For each of the situations below, draw vectors representing the electric field caused by each charge at the point indicated and use them to determine the direction of the net electric field. In each case, the distance from each charge to the point indicated is the same. Also, all charges have the same magnitude, and are positive or negative as indicated. ++ + 0+ + B. Consider the following conversation between two students about how to calculate the +Q net electric field at point A in the situation shown in the figure. Alex: We can use the formula E = kl to calculate one of the electric fields, and since d the other will be the same, we can just double our result to find the total. Genevieve: I don't think we can do that because the electric fields are not in the same direction: one is to the left and the other is down. They are perpendicular, d Who do you agree with? Explain your reasoning. so we need to use the Pythagorean theorem to find the net field. A d +Q C. Let's make the problem in part B concrete: take Q = 4.0 C and d = 10 cm. a. Calculate the magnitude of the net electric field. b. What is the direction of the net electric field? Draw it on the diagram from part B above.. A.
