explain the conditions that would create the largest repulsive interactions between the balloon and metal rod

Repulsive interactions between the balloon and metal rod because metal is an electrical conductor, when you rub the balloon against metal the extra electrons in the balloon quickly leave the balloon and move into the metal so the balloon is no longer attracted and does not adhere.These two fundamental principles of charge interactions phenomena there are two types of electrically charged objects - those that contain more protons than electrons and are said to be positively charged and those that contain fewer protons than electrons and are said to be negatively charged. These two types of electrical charges - positive and negative - are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Oppositely charged objects will exert an attractive influence on each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other.
