Two small aluminum spheres, each of mass 0.0250 kilograms, areseparated by 80.0 centimeters.
how many electrons does each sphere contain? (the atomic mass ofaluminum is 26.982 grams per mole, and its atomic number is13.)
how many electrons would have to be removed from one sphere andadded to the other to cause an attractive force between the spheresof magnitude 1.00*10^{4}n}(roughly one ton)? assume that the spheres may be treated as pointcharges.
what fraction of all the electrons in one of the spheres does thisrepresent?
