6. The dielectric constant of a helium gas at NTP is 1.0000684 . Calculate the electron polarizability of helium atoms if the gas contains $2.7 \times 10^{26}$ atoms $/ \mathrm{m}^{3}$ and hence calculate the radius of helium atom $\left(\varepsilon_{Q}=8.854 \times 10^{-12} \mathrm{Fm}^{-1}\right)$
