This experimental method of determining the surface tension of a liquid is called the Du Nüoy Ring method. The equation for this is:
σ = F/4πR
where
σ is the surface tension
F is the net force acting on the ring
R is the radius of the center ring
σ = F/4πR = [(16 g - 10 g)(1 kg/1000 g)(9.81 m/s²)]/{4π[(10 m + 9.5 m)/4]}
σ = 9.608×10⁻⁴ N/m
Do all you can in one big day that you have time off or work on one thing then work on the other at the same time
The force needed is 5250N
I never did that right there
