There s a loop in between two charges. The charge to the left has a value of +Q. The charge to the right has a value of +2Q. Both charges are the same distance from the loop and are placed along the axis of the loop.
(a) Is the net electric flux through the loop due to the charges positive, negative, or zero? Explain your reasoning
(b) Suppose that the new charge located t the right of the loop had been negative instead of positive. How whould the answer to part (a) change, if at all? Explain
