Answer:
The coulomb force between two charges decreases when a dielectric medium is placed between the charges. the dielectric reduces the electrostatic/coulombs force as compared to vacuum by a factor Er called dielectric constant.
Explanation:
According to Coulomb's law, the electrostatic force between two point charges depends on the product of the charges and the separation between them.
Force is directly proportional to dielectric constant k. So ,increasing diectric constant will increase the force too. Electrostatic force depends on magnitude of charges, distance between the charges and material between them. The dielectric constant does not change because, it is a constant
