Attraction and repulsion, in physics means, is when two objects
attract and repel one another. For example, an When a negatively
charged rod is brought near an electroscope with negatively charged
leaves, the leaves will repel. Same goes for when a positively
charged rod is brought near an electroscope with positively charged
leaves, the leaves will repel. But if a negatively charged rod is
brought near an electroscope with positively charged leaves, the
leaves will attract. Kind of like opposites attract, and likeness
repels.
