Question

What States That Like Charges Repel And Opposite Charges Attract.

Answer 1

Hint: In 1785, a French scientist named Charles Augustin de Coulomb coined a concrete mathematical connection between two electrically charged substances. Coulomb's law, often known as Coulomb's inverse-square law, is an equation describing the force that causes bodies to attract or repel each other.

Complete answer:
Coulomb's law is a mathematical formula that describes the electric force between charged things. It was developed by Charles-Augustin de Coulomb, a French scientist in the 18th century, and is similar to Isaac Newton's law of gravity. The force of attraction or repulsion between two charged things is directly proportional to the product of their charges and inversely proportional to the square of the distance between them, according to Coulomb's law. It acts on the line that connects the two charges that are termed point charges. According to Coulomb's law, "opposite electric charges attract one another whereas comparable charges repel one another."
Both gravitational and electric forces diminish as the square of the distance between the objects grows smaller, and both act along a line between them. Coulomb's law, on the other hand, states that an object's electric charge, not its mass, determines the amount and sign of the electric force. Thus, the impact of electromagnetism on the motion of charged objects is determined by charge. The property of charge is a fundamental attribute of matter. Every atom in the universe has an electric charge that can be positive, negative, or zero. Electrons, for example, have a negative charge, whereas atomic nuclei have a positive charge. The majority of bulk matter contains an equal quantity of positive and negative charge, resulting in a net charge of zero.

Note:
Charges that are similar repel each other, whereas charges that are dissimilar attract each other. A negative charge repels another negative charge, whereas a positive charge attracts a negative charge. Along the line between the two charges, attraction or repulsion occurs. The force is proportional to the square of the distance between the two charges. As a result, doubling the distance between the two charges reduces the attraction or repulsion to one-fourth of its original strength. The magnitude of the force rises by a factor of 100 when the charges are 10 times closer together.
