Point charge 2.5 is located at x = 0, y = 0.30 , point charge -2.5 is located at x = 0 and y = -0.30 . What are (a)the magnitude and (b)direction of the total electric force that these charges exert on a third point charge = 5.0 at x = 0.40 , y = 0?
Learing the Coulomb formula and how to add vectors will enable you to do this problem. We will be glad to critique your work.
