are 13 A mercury drop on a clean horizontal glass surface and a water drop on a horizontal glass plate coated with a thin layer of talcum powder similar in shape If it is known that for a particular shape of a drop surface energy of surface tension and the gravitational potential energy bear a definite ratio that is independent of the size of the drop estimate the ratio masses of these drops Density of mercury is pH 13 60 g cm density of water is pw 1 00 g cm surface tension of mercury is OH 0 46 N m and surface tension of water is ow 0 07 N m
