The rest energy of W⁺ boson is about 80 GeV. What is the range of weak interaction? (h = 6.63 × 10^-34 J·s) A) 2.5 × 10^-15 m B) 2.5 × 10^-18 m C) 2.5 × 10^-17 m D) 2.5 × 10^-19 m

Question

Quizplus · Accepted Answer

The range of the weak interaction is approximately given by the Compton wavelength of the W boson, which is inversely proportional to its mass. Using the relation λ = ħ/(mc), where ħ is the reduced Planck's constant and mc is the energy equivalent of the mass (80 GeV), the range is approximately 2.5 × 10^-18 m.

The Rest Energy of W+ Boson Is About 80 GeV
