If mass of an atom is $M$ moving with speed $v$ , what will be its speed after the emission of an $α$ -particle if speed of $α$ -particle is zero ?

Options:

Answer:

Solution:

$Applying the principle of momentum conservation,$ $M v \Rightarrow v^{'} = (M - 4) v^{'} [∵ the speed of the a-particle is zero] = \frac{M v}{M - 4}$
