Question: command to retrieve a solution

Hi

I have a set of differential equations which I have solved for a specific value, and would like to use the second answer (F__A(V)) in my next calculations

 

What command can I use to retrieve that value?

sol(0.1e-4);
     [V = 0.00001, F__A(V) = HFloat(3.498873118476744e-6), 

       F__B(V) = HFloat(1.9101126881523255e-5), 

       F__C(V) = HFloat(9.550563440761627e-6)]
 

Regards
