Problem 3. Find the force (in newtons) exerted by a water molecule (dipole moment P = 6.225-10-30 C-m) on a carbon atom (polarizability a=1.863-10-40 C.m/N) at a distance r = 1 um if the dipole moment of the water molecule is oriented along the line that joins the molecule with the atom, and if it is perpendicular to this line.
