Approximate the strong force between two protons.

  1. Sep 7, 2013 #1
    1. The problem statement, all variables and given/known data
    2 protons in a Helium nucleus are separated by about 2x10^-15 m. Calculate the approximate magnitude of the strong force holding the 2 protons together.


    2. Relevant equations
    Electromagnetic force equation?


    3. The attempt at a solution
    Okay now im thinking that the strong force is 100 times stronger thn the electromagnetic force.. SO do I calculate the electromagnetic force between two protons and multiply by 100?

    You know that strong force keeps the nucleus together, then the system must be in equilibrium, then the strong force must be equal to the coulomb force between the protons
