Question
Law of conservation of momentum states that:
- The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them.
- Magnitude of the final momenta = magnitude of the initial moment.
-
- All the above
Hint:
Law of conservation of momentum.
The correct answer is: All the above
The law of conservation of momentum states that for two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. So as all the above choices prove the same, all of the above are correct.
