In an alpha decay the kinetic energy of alpha particle is 48 mev
Answers
I think this your question is not very complete and therefore the right answer can not be obtained.
But I would rather give you some highlights on this area of study;
In radioactivity we have emissions such as alpha, beta and the gamma rays.
These radiations have certain amounts of kinetic energies that they are being accompanied with during their emission.
Answer:
your answer is incomplete but I understood your question.
The KE of alpha particle is given as 48Mev and Q value is given as 50Mev.
you have to find the mass number of the nuclei
Explanation:
KE of alpha particle = [A-4/A] Q where A is the mass number.
hence, 48=[A-4/A] 50
48A = 50A -50* 4
48A = 50A -200
2A = 200
A=100 is the answer
i think this may be helpful for you.
