Three point charges lie in a straight line along the y-axis. A charge of q1 = − 9.0 μC is at y = 6.0 m, and a charge of q2 = −8.0 μC is at y = − 4.0m. The net electric force on the third point charge is zero. Where is this charge located?

According to Coulomb’s law, the force between two charges acts along the straight line joining the charges. The force is directly proportional to the product of the charges, and inversely proportional to the square of the distances between the charges. This law is similar to A) the kinetic theory of gases. B) Newton’s third law of motion. C) the first law of thermodynamics. D) the universal law of gravitation.
