Question

How does the coloumb force between two point charges depend upon the dielectric constant of the medium?

Answer 1

The coulomb force between two charges decreases when a dielectric medium is placed in between the charges.
                                                           F=14πε0εr×q1q2r2Force is inversly proportional to εrεr is called the dielectric constant of medium

Answer 2

the formula is q=1/4⚻Eo x q1q2/r^2
