Question
For an interaction of two particles in two dimensions, which of the following is true? The sum of the magnitudes of the momenta of the particles before and after the interaction is the same. The sum of the x-components of the momenta of the two particles before and after the interactions is the same. If the sum of the x-components and the sum of the y-components of the two particles before the interaction are both zero, then the sum of the magnitudes of the momenta after the interaction is also zero. If the sum of the y-components before the interaction is nonzero, then the sum of the y-components of the momenta after the interaction cannot be zero.Explanation / Answer
The sum of the x-components of the momenta of the two particles before and after the interactions is the same If the sum of the y-components before the interaction is nonzero, then the sum of the y-components of the momenta after the interaction cannot be zero are the answers
