1. The problem statement, all variables and given/known data Object A is metallic and electrically neutral. It is charged by induction so that it acquires a charge of -4.6 x 10-6 C. Object B is identical to object A and is also electrically neutral. It is charged by induction so that it acquires a charge of +4.6 x 10-6 C. Find the difference in mass between the charged objects. 2. Relevant equations 3. The attempt at a solution i tried dividing the charge by the charge of one electron/proton which is 1.602x10-9 and then multiplying that by the mass of one electron/proton but i still get the wrong answer!
