Vedclass · Answer

(B) The kinetic energy $E$ of a particle with momentum $P$ and mass $m$ is given by the formula $E = \frac{P^2}{2m}$.Since the momentum $P$ is constant for all particles,we have $E \propto \frac{1}{m}$.This implies that the particle with the smallest mass will possess the maximum kinetic energy.Comparing the masses of the given particles: $m_{	ext{electron}} Therefore,the electron,being the lightest particle,has the maximum kinetic energy.

Four particles are given,all having the same momentum. Which one has the maximum kinetic energy?
