What does Coulomb's Law describe?

• A. The relationship between mass and acceleration.
• B. The electrostatic force between two charged objects.
• C. The energy transformations in a circuit.
• D. The relationship between voltage and current.

Answer: (B)

Coulomb's Law defines the electrostatic force that exists between two charged objects. It states that the force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. This law is fundamental in electrostatics, helping to describe how charged particles interact, whether they are attracting or repelling each other based on their signs (positive or negative).

In contrast, the other options relate to different principles in physics. The relationship between mass and acceleration pertains to Newton's second law of motion, which deals with forces and is not focused on electric charges. The energy transformations in a circuit involve concepts such as Ohm's Law and the conservation of energy, unrelated to charge interaction. Voltage and current are related through Ohm's Law, which describes how electric current flows when voltage is applied in a circuit, separate from the interactions described by Coulomb's Law.
