Two small silver spheres, each with a mass of 10.9 g, are separated by 1.11 m. Compute the fraction of the electrons in one sphere that should be transferred to the other to produce an attractive force of 1.07*104 N (about 1 ton) among the spheres. The number of electrons per atom of silver is 47. (The molar mass of silver is 107.87 g/mol.)
