A film of soap solution is formed on a loop frame loop of 6.28 cm long thread is gently put on the film and the film is broken with a needle inside the loop. The tread loop takes the shape of a circle. Find the tension in the thread. Surface tension of soap solution = 0.030 n//m .

A thin and light thread of sufficient length L is attached to a wire frame. The frame (along with the thread) is dipped into soap solution. When the frame is taken out of the solution, the thread takes the form of a semicircle with a soap film extending between the frame and the thread as shown in the figure ( a ). Now the thread is deformed into two semicircles by applying a force of F at the middle of the thread, as a result the film gets strectched as shown in the figure. ( b ). Calculate the surface tension of the soap solution.
