In this paper we try to describe new method to measure small forces using modified Michelson interferometer. In the setup one of the Michelson interferometer mirrors is replaced with a wire. One end of the wire is fixed and the other end is free. To exert a small force to the wire we used two rods capacitor setup. By changing the applied voltage on the rods, the force on the wire functioning as the mirror is changed and its free end is displaced. By analyzing the interference patterns produced by the wire and the mirror, the displacement is measured precisely and the applied force is deduced. At the end, theoretical force-voltage relation in rod like capacitors and its agreement with experimental data are investigated.
