Conclusion : 1) when we put a glass slab between two charges, it will decrease the electric force between them . 2) When we put a metallic slab between two charges, it will decrease the electric force to zero. WebThe Dielectric constant (K) of the medium is the ratio of the permittivity of the substance (\varepsilon) to permittivity of the free space (ε 0 ). i.e K = ε / ε 0 As Permittivity of medium and permittivity of free space both have same units(F/m ie Farad/meter) dielectric constant becomes dimensionless quantity.
