The electrostatic forces between ellipsoids, between an ellipsoid and a cylinder and between an ellipsoid and a plate which are immersed in a fluid have been evaluated using Derjaguin’s approximation. Both of them in the three cases have different surface potentials of less than 25 mV. We assume that the interaction range between them is distinctly smaller than the lengths of their principal axes and evaluate the electrostatic forces. Examples are given to show the effect of particle size and orientation on electrostatic force
