The force between two point charges placed in a material medium of dielectric constant $\varepsilon_r$ is $F$. If the material is removed, then the force between them becomes
The force between two point charges placed in a material medium of dielectric constant $\varepsilon_r$ is $F$. If the material is removed, then the force between them becomes
Show Hint
Dielectric reduces force → removing it increases force by factor $\varepsilon_r$.
