Question

A massless inextensible string in the form of a loop is placed on a horizontal film of soap solution of surface tension t. if film is pierced inside the loop and it convert into a circular loop of diameter d, then the tension produced in string

Answer 1

Answer:

Tension in the string will be Td.

Step-by-step explanation:

A mass-less in-extensible string as a circle is put on a flat film of cleanser arrangement of surface strain t. In the event, that film is punctured inside the circle and it convert into a round circle of measurement d, at that point the pressure delivered in string will be Td.
