The Strong Nuclear Interaction Has a Range of Approximately 0 $\Delta E \Delta t = \hbar / 2$

Multiple Choice

The strong nuclear interaction has a range of approximately 0.70 *10^-15 m.It is thought that an elementary particle is exchanged between the protons and neutrons,leading to an attractive force.Utilize the uncertainty principle $\Delta E \Delta t = \hbar / 2$ to estimate the mass of the elementary particle if it moves at nearly the speed of light.

A) 140 MeV/c²,a pion
B) 511 keV/c²,an electron
C) 96 GeV/c²,a Z boson
D) 500 MeV/c²,a K meson
E) 106 MeV/c²,a muon
