What happens when a charged insulator is placed near an uncharged metallic object, and how does the presence of the insulator affect the behavior of the metallic object?

When a charged insulator is placed near an uncharged metallic object, the charges in the insulator induce opposite charges in the metallic object through electrostatic induction. This causes the metallic object to become polarized, with one side becoming positively charged and the other side becoming negatively charged. The presence of the insulator affects the behavior of the metallic object by creating an attractive force between the opposite charges, causing the metallic object to be attracted towards the charged insulator.
