A thin metal wire of density ρ floats on water surface horizontally. If it is NOT to sink in water then maximum radius of wire is proportional to ( T = surface tension of water, g = gravitational acceleration)

Question

A thin metal wire of density ρ floats on water surface horizontally. If it is NOT to sink in water then maximum radius of wire is proportional to ( T = surface tension of water, g = gravitational acceleration), 2T π ρ g, π ρ g T, T π ρ g, π ρ g T
