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.

A region around a charged particle that can exert a force on another charged particle is called an

electric pulse.

electric charge.
