answered-by-expert Expert Answer
Force F = (q2) / [ (4πε0) r2 ]; q = 1 C , F = 50×9.8 N , ε0 = 8.85 × 10-12 F/m
 
Separation distance r = [ 1012 / (4π×8.85×50×9.8) ]1/2 = 4283 m

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?
