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

Assertion : if work done in increasing th size of a soap film from 10 cm xx 4 cm to 10cm xx8cm is 2xx10^(-4) J, then the surface tension is 5xx10^(-4)N m^(-1) Reason : work done = surface tension xx increase in area .
