A drop of some liquid of volume $0.04 c m^{3}$ is placed on the surface of a glass slide. Then another glass slide is placed on it in such a way that the liquid forms a thin layer of area 20 $c m^{2}$ between the surface of the two slides. To seperate the slides a force of $16 \times 1 0^{3}$ dyne has to be applied normal to the surface. The surface tension of the liquid is (in dyne $c m^{- 1}$ )
