Consider two hollow glass spheres, one containing water and the other containing mercury. Each liquid fills about one-tenth of the volume of the sphere. In zero gravity environment

water and mercury float freely inside the sphere

water forms a layer on the glass, while mercury floats

mercury forms a layer on the glass, while water floats

water and mercury both form a layer on the glass

Explanation:

In zero gravity the water forms a layer on the glass while mercury floats because the density of mercury is much higher than that of the water so it floats in the zero gravity environment whereas on the other hand water forms a layer on the glass because of the surface tension of water is higher than that of the mercury.The surface tension of mercury is low.Hence option 2 is the correct answer.
