Consider a rubber rod having been rubbed with fur to give the rod a net negative charge, and a glass rod having been rubbed with silk to give it a net positive charge. Compared to their masses before the rods were rubbed with fur and silk,a) both rods have more mass after having been rubbed.b) both rods have less mass after having been rubbed.c) the rubber rod has less mass and the glass rod has more mass than before they were rubbed.d) the rubber rod has more mass and the glass rod has less mass than before they were rubbed.

The rubber rod having been rubbed with fur get a net negative charge thereby gaining more mass which means the mass has increased compared to before it was rubbed against the fur while the glass rod having been rubbed with the silk to give it a net positive has lost mass and therefore has less mass compared to before it was rubbed on the silk.

After being charged by contact by the fur and silk, the rubber rod has more mass and the glass rod has less mass.

From the information given, a rubber rod has been rubbed with fur in order to give the rod a negative charge while the glass rod has a net positive charge.

In this case, when the contact with the fur and silk has resulted in a charge, this will lead to the rubber rod having more mass and the glass rod having less mass. The rubber rod gets electrons while the glass rod loses electrons.
