(The atomic mass of aluminum is 26.982 g/mol, and its atomic number is 13.) (b) How many electrons would have to be removed from one sphere and added to the other to cause (c) What fraction of all the electrons in each sphere does this represent? attractive force between the spheres of magnitude 1.00 x 10¹ N (roughly one ton)? Assume that the spheres may be treated as point charges.
