Two equal masses m are attached with a massless string of length L.The string is tight and the masses are moving in uniform circular motion with speed v about the system's center of mass. The string is on fire and breaks . There is no gravity or other external forces on the system. What is the angular momentum of the system after the collision.

Zero
After the string breaks there is no angular momentum because the two masses are moving with linear motion. Of course the same energy is there, or is it? what do you think?

angular momentum will be = 2mvl
since after the sring breaks both move with same velocity "v"
