Tags: A U-shaped wire is dipped in a soap solution , A wire ring of 5cm redius is rested on the surface of a liquid and then reaised. The pull required is 3.14g more before the film breaks than it is afterwards. Find the surface tension of the liquid ,
A U-shaped wire is dipped in a soap solution, and removed. A thin soap film formed between the wire and a light slider supports a weight of 1.5×10^−2N (which includes the small weigh of the slider). The length of the slider is 30cm. What is the surface tension of the film?
