Question

-decay of a parent nucleus X results in a daughter nucleus Y. If m_x ,m_y and m_a are the masses of the parent nucleus, the daughter nucleus and the - particle respectively, then the net kinetic energy gained in the process is

Accepted Answer

Correct answer: B. (a) _2 He^4+X Y The net kinetic energy gained in the process E=(m_x+m_a-m_y)c^2

$α -decay of a parent nucleus X results in a daughter nucleus Y. If m_{x}, m_{y} and m_{a} are the masses of the parent nucleus, the daughter nucleus and the α - particle respectively, then the net kinetic energy gained in the process is$
