A soap film in stretched over a reclangular vertical wire frame as shown in the figure, what forces hold section abod in equilibrium ?

A soap film is created in a small wire frame as shown in the figure. The sliding wire of mass m is given a velocity u to the right and assume that u is small enough so that film does not break. Plane of the film is horizontal and surface tension is T, then time to region the original position of wire is equal to :

Wires each of resistance R form a cubical wire frame as shown in figure. Match the following.

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 wire is wound over a pencil and placed over a scale as shown in the figure. The diameter of the given wire is "________" .

A light wire AB of length 10 cm can slide on a vertical frame as shown in figure. There is a film of soap solution trapped between the frame and the wire. Find the load W that should be suspended from the wire to keep it in equilibrium. Neglect friction. Surface tension of soat solution =25 dyne cm^-1 . Take g=10 ms^-2
