What happens when two objects have opposite charges?

• A. They attract
• B. They repel
• C. They become neutral
• D. They exchange charge

Answer: (A)

Opposite electric charges attract each other. The electrostatic force between two charges pulls them toward one another, and its direction is along the line joining the charges. The strength increases with larger charges and with shorter separation, following Coulomb’s law: the force grows as the product of the charges and falls with the square of the distance. They don’t automatically become neutral just by having opposite charges; they stay charged unless some charge transfer or neutralization occurs (for example, if they touch and are conductive). The key observable effect here is the attraction between the two charges.
