A +10nC charge is located at (x, y) = (0 cm, 10 cm) and a -5.0 nC charge is located (x, y) = (5.0 cm, 0 cm). Where would a -10 nC charge need to be located in order that the electric field at the origin be zero?

Greg drew a diagram to compare two of the fundamental forces. which labels belong in the areas marked x, y and z? gravitational force electromagnetic force x. attractive y repulsive z: infinite range x: infinite range y attractive z. repulsive x. always attractive y: infinite range z: attractive or repulsive x. attractive or repulsive y infinite range z: always attractive
