Figure below shows a wire loop with a string that has been dipped into soap solution.

i) Sketch a similar diagram to show the observed effect if the soap film is punctured at X
ii) Explain the observations made in (i) above

Answers

ii) When side x of the film is broken, surface tension acts only on one side Y of the film;
surface tension of the film tends to make the surface area to be minimum hence it pulls
the string to make a smooth curve
