In a nuclear reaction of $α$ -decay, the alpha particle moves with kinetic energy $E$ . The total energy released if parent nuclei was at rest will be

Options:

Answer:

Solution:

By momentum conservation,

$2 A E_{A} = 2 (4) E$

$E_{A} = \frac{4}{A} E$

Energy released is

$E_{R} = E + \frac{4}{A} E = E (1 + \frac{4}{A})$
