3. The loop shown at right has an area A. a. The loop is held to the right of a positive point charge shown. i. Draw and label an area

vector for the surface bounded by the loop. ii. Sketch electric field lines to represent the electric field due to the charge. iii. Is the electric flux through the loop due to the charge positive, negative, or zero? Explain your reasoning. b. A positive charge with twice the value of the initial charge is now placed to the right of the loop as shown. Both charges are the same distance from the loop and are placed along the axis of the loop. Is the net electric flux through the loop due to the charges positive, negative, or zero? Explain your reasoning. (Note:Use the same area vector you used in part a.) c. Suppose that the new charge located to the right of the loop had been negative instead of positive. How would your answer to part b change, if at all? Explain.
