Vedclass · Answer

(C) The kinetic energy $KE$ of a particle is related to its momentum $p$ and mass $m$ by the formula: $KE = \frac{p^2}{2m}$.Since all four particles have the same momentum $p$,the kinetic energy is inversely proportional to the mass $(KE \propto \frac{1}{m})$.Therefore,the particle with the smallest mass will have the maximum kinetic energy.Comparing the masses: $\frac{m}{2} The particle $A$ has the smallest mass,$\frac{m}{2}$.Thus,particle $A$ has the maximum kinetic energy.

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