Between two parallel long wires AB and CD is a soap film S between another two transverse wires PQ EF The separation between PQ EF is x which can be varied The correct statement s is are Force due to surface tension on PQ equals in magnitude to that on EF Force of surface tension on PQ is proportional to the separation x Force of surface tension on PQ is proportional to length of PQ Surface energy depends on x P JB
