Question

when the relative permittivity of the medium is increased the force between two charges placed at a given distance apart​

Answer 1

Explanation:

Dielectric constant of medium =εr

Dielectric constant of medium =εrForce in the medium  =Fm

Dielectric constant of medium =εrForce in the medium  =FmThe electric force between point charges in the presence of medium is given by

Dielectric constant of medium =εrForce in the medium  =FmThe electric force between point charges in the presence of medium is given byFm=εrFair

Dielectric constant of medium =εrForce in the medium  =FmThe electric force between point charges in the presence of medium is given byFm=εrFairFair=Fm×εr=F⋅εr.

Answer 2

Answer:

But the relative permittivity can vary and the force is inversely proportional to it. So, as permittivity of medium increases, the magnitude of force decreases.
