Explanation

The susceptibility of free space or air is zero (0). In free space, the relative permittivity (εr) is equal to 1, and the susceptibility (χe) is given by χe = εr - 1 = 1 - 1 = 0. This means that free space does not exhibit any polarization or ability to become polarized under the influence of an electric field.
