A rectangular film of a certain liquid is 5 cms long and 3 cms is breadth. If the amount of work done in increasing its size to `6cmxx5cms" is "3xx10^(-4)J` then the value of surface tension of the liquid is-

Select and write the most appropriate answer from the given alternative for each sub-question : A rectangular film of a liquid is 5 cm long and 4 cm wide. If the work done in increasing its ara to 7 cm xx 5 cm is 0.06 J, the surface tension of the solution is :

The work done in increasing the size of a soap film from 10cmxx6cm to 10cmxx11cm is 3xx10^-4 Joule. The surface tension of the film is

If work done in increasing the size of a soap film from 10cmxx6cmxx to 10cmxx11xm is 2xx10^-4H , then the surface tension is

The work done in increasing the size film with dimensions 8cm xx3.75xm to 10cmxx6cm is 2xx10^(-4)J . The surface tension of the film in (N)/(m) is

The workdone in increasing the size of a soap film from 10 cm xx 6 cm to 10 cm xx 11 cm is 3 xx 10^(-4)J. The surface tension of the film is

If work done in increasing the size of a soap film from 10 cm x 6 cm to 10 cm x 11 cm is 2xx10^(-4) J , then the surface tension is

The work done is increasing the size of a soap film from 10 cm xx 6 cm to 10 cm xx 11 cm is 3 xx 10^(-4) joule. The surface tension of the film is

The work done in increasing the size of a soap film from 10 cm × 6 cm to 10 cm × 11 cm is 3 xx10^(-4) joule . The surface tension of the film is
