Objects that have opposite charges

• are attracted to each other, and the force between the objects pulls them together.

• are attracted to each other, and the force between the objects pushes them apart.

• are repelled by each other, and the force between the objects pulls them together.

If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

• friction destroyed electrons in the rod.

• the silk has become negatively charged.

• protons have moved to the rod.

• glass attracts more protons.

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

• friction.

• convection.

• induction.

• conduction.
