Homework Help: Physics... Coulomb's law

Posted by ~christina~ on Sunday, March 30, 2008 at 9:14am.

Two small silver spheres with a mass of 10.0g, are seperated by 1.00m. Calcuate the fraction of the electrons in one sphere that must be transfered to the other to produce an attractive force of 1.00x10^4 N (about 1 ton) between spheres (number of electrons per atom of silver is 47, and the number of atoms per gram is avogadro's number divided by the molar mass of silver, 107.87g/mol.

I have no idea how to do this.

I know Coulomb's law is Fe= (|q1|q2|)/r^2 but how to find the "fraction" of electrons in one sphere..


help please
