Mathematically, the potential of weak interactions is given by
V(r)=αW(e^−r/a)/r⇐ weak potential
V(r)=αEM1/r⇐ electromagnetic potential
For the weak potential, the parameter a controls the range of the force.
This type of potential is called a Yukawa potential.
Taking a=2×10^−18 m
and assuming αW=αEM,
what are the ratios of the weak potential to the EM potential at r=2×10^−20 meters? Give answer to two significant figures.
