Electron Distribution

How will charges be distributed if the negatively charged rod touches the white box shown. The white box represents a conductor. The gray box represents an insulator.

• Negative charges will be evenly distributed throughout all 3 boxes.

• Negative charges will be evenly distributed throughout the 2 white boxes.

• Negative charges will be evenly distributed throughout the first white box and the gray box only.

• Negative charges will be evenly distributed throughout the first white box only.
