# Coulombâ€™s Law

## What is the significance of Coulombâ€™s constant?

Coulombâ€™s constant (k) determines the magnitude of the electrostatic force in a given medium. It varies with the permittivity of the medium, being higher in a vacuum and lower in other media. Coulombâ€™s Law not only helps in understanding the natural phenomena related to charges but also serves as a building block for more complex theories in electromagnetism and quantum physics, highlighting the interconnectivity of science across various domains.

## Can Coulombâ€™s Law be used for charged spheres?

Coulombâ€™s Law can be applied to spheres if they are considered as point charges located at their centers, provided the distance between them is much greater than their radii.

## How does the distance between charges affect the force?

The force is inversely proportional to the square of the distance between the charges. As the distance increases, the force decreases rapidly.
