The excess number of electrons  N=qe=3.0⋅10−61.6⋅10−19  The corresponding increase in mass  m=(1.9⋅1013)(9.11⋅10−31)  =1.7⋅10−17kg  Since both objects carry charge of the same magnitude,N is also equal to the number of electrons lost by object B. Hence, the mass of B is reduced by the amount?  the difference in mass between the chargedobjects and state which has the greater mass  M=(M+m)-(M-m)  =2m=3.4⋅10−17kg  object A has larger mass.
