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.

What do YOU think ?
While we're happy to HELP we won't do all the work for you.
Show us what you have done and where you are having problems..

I have tried to put the values
see if you take the ratio of the two potential than the denominator will be canceled and also the constant so just what we have to do is that do e^−r/a and putting the values we get 0.99 or 1 so the ratio should be 1:1
But that's not the right answer my teacher isn't accepting
