The rest energy of ? meson is about 140 MeV. What is the range of strong force? (h = 6.63 × 10^-34 J·s) A) 0.7 × 10^-15 m B) 1.8 × 10^-15 m C) 1.4 × 10^-15 m D) 2.5 × 10^-15 m

Question

Quizplus · Accepted Answer

The range of the strong force can be estimated using the uncertainty principle and the rest energy of the meson. The range is approximately given by ħc/E, where ħ is the reduced Planck's constant and E is the energy. Using the given energy of 140 MeV, the range is approximately 1.4 × 10^-15 m.
