Four particles A, B, C, D of mass m 2 , m, 2 m, 4 m , have same momentum, respectively. The particle with maximum kinetic energy is :

Options

  1. AB
  2. BA
  3. CD
  4. DC

Correct answer

B. A

Step-by-step solution

KE = p ^2 2 ~m Same momentum, so less mass means more KE. So m 2 will have max. KE .
