Interesting physics. The surface tension of a liquid

Condition of the given problem. A thin wire ring with a diameter of 34 mm, suspended from a spring with a pointer is immersed in a vessel with water. Noting the position of the pointer on the scale, slowly lowered into the vessel. The spring is stretched. At the time of separation of the ring from the liquid again mark the position of the pointer. What is the value of the surface tension of the water obtained if the spring is stretched to 32 mm. spring Stiffness 0.5 N/m. How long would the spring have laste
