a drop of some liquid of volume 0.04cm^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 20cm^2 between the surfaces of the two slides.to separate the slides a force of 16*10^5 dyne has to be applied normal to the surfaces,the surface tension of the liquid is (in dyne /cm)
