Let , and denote the magnitudes of net force by a proton on a proton, by a proton on a neutron and b — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Nuclear force is strong and attractive and is identical between nucleons. However, for two protons, there is an additional electrostatic Coulomb repulsion which reduces the net attractive force. Thus, $F_{pp} < F_{pn} = F_{nn}$. Therefore, correct answer is D.
