The following particles move with same kinetic energy. Which of them has maximum momentum? (1) Electron (2) Proton (3) Deutron (4) Alpha Particle

1 Answer

Answer :

(4) Alpha Particle Explanation: The formula for kinetic energy in terms of momentum for fundamental particles is basically just a quantized version of the classical formula, KE=(P^2)/2m, where KE is kinetic energy, p is momentum and m is the particle’s mass.
