In this paper, a "two-molecule" model of ellipsoidal drop was established.And then the ellipsoid situation was transformed into sphere situation by coordinate transformation.By utilizing bipolar coordinates and Maxwell stress tensor, the expression of electrostatic radial and tangential forces between two drops was deduced.
