Solution


Q.

Four particles A, B, C, D of mass m2,m,2m,4m have same momentum, respectively. The particle with maximum kinetic energy is:                       [2024]
1 A  
2 D  
3 B  
4 C  

Ans.

(1)    

         Kinetic energy = P22m

         P⇒ momentum (same for all)

         KE∝1mass

         Particle A is of least mass, has maximum kinetic energy
