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

Options

  1. AM v M+2
  2. BM v M-4
  3. CM v M+4
  4. DM-4 M N .

Correct answer

B. M v M-4

Step-by-step solution

Applying the principle of momentum conservation, aligned M v & =(M-4) v^ [ array r the speed of the a-particle is zero ] array . v^ & = M v M-4 aligned
