Problem

A neutron is placed successively at three positions relative to a fixed proton: (I) 0.8×10−15 m0.8\times10^{-15}\,\text{m}, (II) 5×10−15 m5\times10^{-15}\,\text{m}, and (III) 1×10−10 m1\times10^{-10}\,\text{m}. Which sequence correctly identifies the fundamental force that predominantly governs the neutron–proton interaction at each position? a) Strong, Weak, Gravitational b) Strong, Electromagnetic, Gravitational c) Electromagnetic, Strong, Gravitational d) Strong, Gravitational, Gravitational
