is 
MeV.
Text Solution
Verified by ExpertsThe correct answer is:
4
(4)
The formula to calculate the Q-value of the given nuclear reaction can be written as
..(i)
Substitute the values of the known parameters into equation (i) to calculate the required Q-value for the reaction.
Q = (238.05060 u - 234.04360 u - 4.00260 u)c 2 = 0.0044c
2 x 931.5 MeV/c 2 
4 MeV
