Question
In nucleus of mass number A, originally at rest, emits an a - particle with speed v. The daughter nucleus recoils with a
Options
A.
B.
C.
D.
Solution
Applying law of conservation of momentum
MV = mv
Let mass of each proton = m
Mass of daughter nucleus =(Am - 4m)
Mass of α-particle = 4m
So,(Am - 4m)V = 4m ×
V =
MV = mv
Let mass of each proton = m
Mass of daughter nucleus =(Am - 4m)
Mass of α-particle = 4m
So,(Am - 4m)V = 4m ×
V =
