With the two spheres separated by 1 cm you measure the magnitude of the force between the spheres to be LaTeX: F_{12}F 12 . Now you remove the second sphere, and then bring a third identical sphere that is initially uncharged into brief contact with the first sphere before separating them by 1 cm. What is the approximate magnitude of the force between the first and third spheres?
