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 square wire frame of length l is dipped in a solution. When the frame is taken out, a liquid film is formed. What is the algebraic sum of all the force acting on the frame due to surface tension of the liquid? (given sigma= surface tension of the liquid).

A square framed with a wire of side 'L' is dipped in a liquid. On taking out, a membrane is formed. What will be the force acting on the frame if the surface ' tension of liquid is S?

A square wire frame of L is dipped in a liquid, on taking out a membrane is formed. If the surface tension of liquid is T, force acting on the frame will be
