3 Electromagnetic Force and Strong Force An atomic nucleus contains two types of particles: protons and neutrons. Neutrons have no charge, while protons have a positive charge of 1.6 x 10-19 C. All nucleons interact via the attractive strong force. To hold the nucleus together, the strong force must overcome the Coulomb repulsion of the protons in the nucleus. (a) A helium-4 nucleus (a particle) contains two neutrons and two protons. It has a radius of about 2 × 10-¹5 m. Estimate the electrostatic potential energy of the two protons. (b) The nuclear binding energy of the a particle includes contributions from the attractive strong interaction of protons and neutrons as well as the repulsive electrostatic interaction of the protons. To get some idea of the relative importance of the two interactions, calculate the ratio of the energy you found in part (a) to the nuclear binding energy of the He nucleus.
