The force between two charges in free space is F. If a dielectric medium of dielectric constant K is placed the force between two charges is…………

The Coulomb force of attraction between two charges separated by a distance is 4N. If a dielectric medium of dielectric constant 2 is kept to fill the space between them, the force of attraction now becomes

Gauss' law governs the force between two charges.

Force between two charges is governed by Ampere's law.

The space between the capacitor plates is filled with a dielectric of dielectric constant K. How will the capacity change ?
