Final answer:
The correct answers are that the electrostatic force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them, according to Coulomb's Law.
Step-by-step explanation:
According to Coulomb's Law, the force exerted by two charges is proportional to the product of the charges (option b) and inversely proportional to the square of the distance between the charges (option a). This relationship makes Coulomb's Law an inverse-square law because the force is proportional to 1 divided by the distance squared (F ∞ 1/r²).
Coulomb’s Law states that for two charged particles or objects, the electric force between them is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. This law is a fundamental principle in electrostatics and is key to understanding the interactions between charged particles.
