A neutron travels at a speed of 1.4 × 107 m/s. Nuclear forces are of very short range, being essentially zero outside a nucleus but very strong inside. If the neutron is captured and brought to rest by a nucleus whose diameter is 1.0 × 10-14 m, what is the minimum magnitude of the force, presumed to be constant, that acts on this neutron? The neutron’s mass is 1.67 × 10-27 kg.
