Question

Is Coulomb’s law universal law? Why?

Answer 1

Explanation:

1. Definition of Coulomb's law: The product of the charges and the square of the distance between them determines the force of attraction or repulsion between two electric charges in a straight line.
2. For a large number of charges, Coulomb's law follows the superposition principle. If the size of the charged body is finite and not negligible in comparison to the distance between the two charged bodies, the law cannot be applied.
3. Coulomb's law does not apply to all situations.
4. The force is directed in the direction of the straight line that connects them.
5. Coulomb's law only applies to point charges, not charge distributions, because the rule only applies in specific circumstances, it is not a universal law.

Since Coulomb's law only applies to point charges and not the distribution of charges, it cannot be considered a universal law. The law is not an absolute rule because it only applies in specific circumstances.
