Find the elctric force between two protons separated at a separation of 1 fermi . the protons in a nucleus remain at a separation of this order.

force between protons = e2/ [ (4πε0)r2 ] ; where e = 1.602 × 10-19 C , 1/(4πε0) = 8.99×109 and r = 1 fermi = 10-15 m;
 
force = (1.602)2×10-38×8.99×109×1030 = 231 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?
