• Positive and negative
• positive and neutral
• negative and negative

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.

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.
• are repelled by each other, and the force between the objects pushes them apart.
