Which of the following in not the unit of surface tension ?

Surface tension of a liquid is a molecular phenomenon of liquids involving the force of cohesion along the liquid molecules. It is scalar quantity and is numberically equal to the surface energy. Numerically, it is proved that the potential soluble salts and surface active substance. Sparingly soluble salts and surface active substances decrease the surface tension of the liquid. However, the fairly soluble solutes increase the surface tension of the liquid. Surface tension of a liquid is independent of surface area but it depends on the intermolecular forces and the temperature. Which among the following is not the unit of surface tension ?

An annular disc of radius r_(1 )= 10 cm and r_(2) = 5 cm is placed on a water surface. Find the surface tension force on the disc if we want to pull it from water surface. Take coefficient of surface tension as sigma= 7 xx10^(-3) N//m, g = 10 ms^(-12) .
