When uncharged bits of paper are brought near a charged rod:

• There is no interaction because the paper is not charged.

• There is no interaction because the paper is too heavy to move.

• There is attraction because the paper is a neutral.

• There is repulsion because the paper is a neutral.

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.

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

• electric pulse.
• electric charge.
• electric force.
• electric field.
