Calculate the coulomb ' force between the two alpha-particles separated by a distance 3.2x10^3 ?

Units for distance is missing. I assume the distance 3.2×103 m. If units are different, use the appropriate multiplication factor for answer.
 
Force = (2e)(2e)/{ 4πε0×d2 }, where e is fundmental charge and d is the distance between the alpha particles.
 
Force = (4×1.602×1.602×10-38)×8.99×109 /(3.2×3.2×106)  = 9×10-35 N

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
