Photoelectric EffectHard
Question
In an α-decay the Kinetic energy of a particle is 48 MeV and Q-value of the reaction is 50 MeV. The mass number of the mother nucleus is:- (Assume that daughter nucleus is in ground state)
Options
A.96
B.100
C.104
D.none of these
Solution
We have Kα = 
. Q ⇒ Kα = 
. Q ⇒ 48 = 
.50 ⇒ A = 100
. Q ⇒ Kα = . Q ⇒ 48 = .50 ⇒ A = 100 Create a free account to view solution
