Coulomb's law is true for:
Correct answer: D. All of the Distances
- A. Atomic Distance
- B. Nuclear Distance
- C. Charged Particle
- D. All of the Distances
Explanation
Correct option is D. Coulomb's law is true for all distances, including atomic distances, nuclear distances, and charged particles. It is a fundamental law of physics that describes the force of attraction or repulsion between two charged objects. The force is inversely proportional to the square of the distance between the objects, so it gets weaker as the distance gets larger. However, the force is still present even at very large distances.There is no evidence that Coulomb's law breaks down at any distance. It has been verified experimentally for distances as small as atomic nuclei and as large as galaxies. Therefore, it is generally believed that Coulomb's law is a universal law that applies to all distances.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
