Assignment:
Object A is metallic and electrically neutral. It is charged by induction so that it acquires a charge of -3.0 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 +3.0 x 10^-6 C. What is the difference in mass between the charged objects and which has the greater mass?
