A nucleus with mass number 220 initially at rest emits an α-particle .
If the Q value of the reaction is 5.5 MeV , Calculate Kinetic Energy of the α - particle
(A) 4.4 MeV
(B) 5.4 MeV
(C) 5.6 MeV
(D) 6.5 MeV

19k.e of (product nucleus + outgoing particle ) - k.e. of incoming nucleus = Q =5.5 MeV
k.e. of product nucleus = 0(as it at rest)
..outgoing particle is the α-particle
....now proceed ! ( i feel i am getting a different answer here ) !
