Задача id9113

A drop of mercury lies on a horizontal plane without wetting it. What should be the size of the drop so that its shape is close to spherical? Assume that for this, the hydrostatic pressure in the drop should be no more than 10% of the pressure created by the surface layer. (The density of mercury is 13,600 kg/m3, and its surface tension coefficient - 0.47 n/m.)
