Aiden has two metal spheres that attract each other with an electrostatic force of 144 N when separated by 25.0 cm. Curious about what charge each sphere has, he decides to use Coulomb's law to help h im o ut. He connects the spheres by a thin conducting wire. When the wire is removed the spheres repel each other with a force of 32.4 N at the same distance. What are the initial charges of the spheres?
