A soap film is formed on a rectangular frame of 7 cm side dipping into a scop solution. The frame hangs from the arm of a balance. An extra weight of 0.4 gram is to be placed in the opposite pan to balance the pull on the frame. Caluclate the surface tension of the soap solution.

A soap film is formed on a rectangular frame of length 7 cm dipping in soap solution. The frame hanges from the arm of a balance. An extra weight of 0.38 g is to be placed in the opposite pan to balance the pull on the frame. Calculate the surface tension of the soap solution. "Given" g= 980 "cms"^(-2).

A soap film is formed in a rectangular frame of length 7 xx 10^(-2) m when it is dipped in soap solution. A weight of 0.4 xx 10^(-3) kg is required to pull the frame . Surface tension of the soap solution is

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 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 rectangular wire frame of size 2 cm xx 2 cm, is dipped in a soap solution and taken out. A soap film is formed, it the size of the film is changed to 3 cm x 3 cm, 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 .

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).
