Two particles, each of mass 1 kg, move with velocities 10î m/s and 2î + 4ĵ m/s respectively before the collision. If these particles stick after the collision, then the final momentum of the system in the center of mass frame is
1
Zero
2
12î + 4ĵ kg-m/s
3
8î + 4ĵ kg-m/s
4
More than one of the above
5
None of the above
