What law states that like charges repel and unlike charges attract?

• A. Coulomb's law
• B. Ohm's law
• C. Newton's law
• D. Faraday's law

Answer: (A)

Coulomb's law describes the electrical force between charges. It states that the force depends on the product of the two charges and is inversely related to the square of the distance between them; the force is repulsive for like charges and attractive for opposite charges. This directly explains why like charges push apart and unlike charges pull together, capturing the behavior described in the statement. Other laws mentioned relate to different phenomena: Ohm's law connects voltage, current, and resistance in circuits; Newton's laws describe motion and forces on objects; Faraday's law concerns the induction of voltage by changing magnetic fields.
