How will charges be distributed a few seconds after a negatively charged rod touched the material shown. The gray box represents an insulator. The white box represents a conductor.

• The middle white being touched is the only box that will have negative charges evenly distributed throughout.

• The 3 white boxes will have negative charges evenly distributed throughout.

• All 4 boxes will have negative charges evenly distributed throughout.

• The two white boxes on the right will have negative charges evenly distributed throughout.
