In a simple model of the helium atom, two electrons orbit a nucleus consisting of two protons and two neutrons. Is the magnitude of the force exerted on the nucleus by one of the electrons greater than, less than, or equal to the force exerted on that electron by the nucleus? What is the Coulomb force between the neutron and the electron?
