Two negatively-charged objects are located on the x-axis equally disstant from the origin as shown. Consider the electric field at the point P1. How will that electric field change fi a third object with a charge +q is placed at point P2? Note: the point P2 is the same distance from the origin as the point P1 and the magnitude of each of the charges is the same. Explain.
