A) \[\frac{2v}{A-4}\]
B) \[\frac{2v}{A+4}\]
C) \[\frac{4v}{A-4}\]
D) \[\frac{4v}{A+4}\]
Correct Answer: C
Solution :
The initial momentum of the nucleus would be equal to \[4{{u}_{H}}v,\] where \[{{\text{u}}_{\text{H}}}\] is the unit mass of hydrogen. Since the mass of hydrogen is 1, so the initial momentum can be given by 4v. The final momentum of the nucleus would be equal to (A - 4)V, where V is the final velocity. Thus, we get from the conservation of momentum, (A - 4)V = 4v, so \[V=\frac{4v}{(A-4)}.\]You need to login to perform this action.
