Calculate the induced dipole moment per unit volume (polarization density) of helium gas when it is placed in a field of 6 x 105 V/m. The atomic polarizability of helium is 0.18 x 100 Fm² and the concentration of helium atom is 2.6 x 1025/m³. Also calculate the separation of positive and negative charges in each atom.
