Suppose we have a positively charged object near a conductor. What happens to the charge distribution of the conductor when we bring an identical positively charged object near to the other side of the conductor? The situation is pictured to the right.

• Electrons in a conductor can move easily through the material.
• The conductor is neutral (total charge is $0 \text{ C}$).
• Opposites attract, so negatively charged electrons tend to be attracted to positively charged objects.
• A smaller distance between charges means a stronger interaction.

• What will the charge distribution in the neutral conductor look like?

• The charge distribution is not affected by which charged object was nearby first.
• The setup of the charged objects and the neutral conductor is symmetric.
• The objects are not touching the conductor, but are close enough to affect the charge distribution.

• In our diagram, we can represent electrons with red subtraction signs, and we can represent the positive nuclei they leave behind with blue addition signs.
