Question
(5%) Problem 19: Consider the following table, which lists the four fundamental forces in our universe. It gives the quantum particles which carry the force, the relative strength (relative to the strongest, the strong nuclear force), the range, and the direction the force acts in. Whenever we talk about the relative strengths of these forces, we are actually talking about approximate strengths only, and usually for the current epoch of the universe. In the early universe, we expect that (except for the gravitational force), the forces all hadNuclear the same strength.

All content © 2018 Expert TA, LLCExplanation / Answer
(a)The ratio of weak nuclear force to strong nuclear force is
F_w/F_s = 10^-13/1
= 10^-13
(b)
the ratio of weak nuclear force to the electromagnetic force is
F_w/F_E = 10^-13/10^-2
= 10^-11
