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?
