A drop of liquid of density is floating half immersed in a liquid of density and surface tension N . The radius of drop in cm will be (g = 10 )

Answer: (1)

Solution

For the drop to float half immersed, the forces on it balance: its weight acts downward, the buoyant force acts upward, and the surface tension force supports the difference . So R^{3}$ρ g -
