A circular ring (radius = 5.0 cm) is used to determine the surface tension of a liquid. e plane of the ring is positioned so that it is parallel to the surface of the liquid. The g is immersed in the liquid and then pulled upward, so a film is formed between the g and the liquid. In addition to the ring's weight, an upward force of 3.6 x 10 N is quired to lift the ring to the point where it just breaks free of the surface. What is the face tension of the liquid?

Question
Transcribed Image Text:2. A circular ring (radius = 5.0 cm) is used to determine the surface tension of a liquid.
The plane of the ring is positioned so that it is parallel to the surface of the liquid. The
ring is immersed in the liquid and then pulled upward, so a film is formed between the
ring and the liquid. In addition to the ring's weight, an upward force of 3.6 x 10 N is
required to lift the ring to the point where it just breaks free of the surface. What is the
surface tension of the liquid?
