Coulomb interaction

Coulomb interaction refers to the force between electric charges. Like charges, such as two positive or two negative, repel each other, while opposite charges, one positive and one negative, attract each other. This force depends on the size of the charges and how far apart they are—the closer they are, the stronger the force. Coulomb's law describes this relationship mathematically. It’s fundamental in understanding how atoms and molecules behave, as it determines how particles like electrons and protons interact, influencing the structure and stability of matter.
