The buildup of electric charges is called . . .

• static electricity

• electric discharge

• electric charge

An object becomes charged when the atoms in the object gain or lose

• electrons
• protons
• neutrons
• all of the above

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.

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.
