A square frame of length L is immersed in a soap solution and taken out. The force experienced by the square plate is........

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.

A rectangle wire frame of size 2cm xx 2cm is dipped in a soap solution and taken out. A soap film is changed to 3cm xx 3cm . Calculate the work done in the process. The surface tension of soap film is 3 xx 10^-2 N//m .

A rectengular wire frame of size 2 cm xx 2 cm, is dipped in a soap solution and taken out. A soap film is formed, if the size of the film is changed to 3 cm xx 3 cm, calculate the work done in the process. The surface tension of soap film is 3 xx 10^(-2) N/m .
