    objects and charges-physics basically

    Object A is metallic and electrically neutral. It is charged by induction so that it acquires a charge of -3.05E-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 +3.05E-6 C. Calculate the difference in mass between the charged objects.

    please help

    How many electrons are acquired by object B? Remember that the charge on one electron is 1.6 \times 10^{-19}~C and that the -3.05 \times 10^{-6}~C charge must be a multiple of the electron charge.
