When strech a thread on both the sides, with equal force acting both the sides the net force is 0. But after that the thread will cut. If force acting is 0 how will the thread overcome surface tension, how will it cut?

Dear student,Here I would like to mention that surface tension is basically taken in to consideration for liquid surfaces.But here the thread will be solid in nature so there will be no use of taking surface tension in account.so if thread is cut surface tension will not play its role but there will be the force which will cause the elasticity to play its role.Regards
