Find the magnitudeof the electric field at the origin (at point (0,0) ) due to two charges.The first is a +9 mC charge directly 8 m to the left of the origin/at point (-8, 0). The second is +3 mC of charge that is 5 meters directly to the right of the origin (at point (5,0).

Express the magnitude as positive if the electric field is to the right, and negative if to the left.
