Homework Statement
Calculate the typical energy of nuclei in solar core. Calculate thermal energy required for a proton to overcome the Coulomb barrier and get within range of strong nuclear force (10^-15m)
Homework Equations
None given
The Attempt at a Solution
I have the core temp as 1.5 x 10^6 K. I know that typical nuclei will have mass mp which is 1.67 x 10^-27kg.
I am sure there must be a simple equation to work this out, but I've never come across it before! I know that the point of the question is to illustrate that fusion reactions would not occur at this temp without quantum tunneling. (Eg typical thermal energy is NOT enough to overcome Coulomb barrier.)
