Four particles have the same momentum which has maximum kinetic energy?

  1. Proton
  2. Electron
  3. Deuteron
  4. α-particle


Answer:

Four particles have the same momentum which has maximum kinetic energy: Electron

Helping Concept:

  1. Kinetic energy = p2/2m
  2. ⇒ K.E ∝ 1/m
  3. Because the electron has less mass as compared to other particles, so it has large momentum.
