Two Particles Interact Through the Weak Force by Exchanging a Z

Question 37

Multiple Choice

Two particles interact through the weak force by exchanging a Z boson,which has a rest mass of 91 GeV/c2.If energy fluctuations given by the Heisenberg uncertainty principle which produced the Z boson allow it to exist only for short times,estimate the maximum range of the weak force.
