what is the answer for all of these. please help me

> Quiz 6 Consider two protons separated by 2.83 x 10-15 m (10-15 m is a femto metre, which is a typical separation in a nucleus). m Part 1) What is the magnitude of the Coulomb force between these protons? Fc = N Part 2) What is the gravitational force between these two protons? FG = N Part 3) Assume that the protons are in equilibrium inside the nucleus. This requires another force, the strong nuclear force. What is the magnitud of this force if only the two protons are found in this nucleus? Fs N
