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.

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.
