Sort by:

Electron As momentum(P) = $$\sqrt{2*M*E}$$ Where M = mass of particle and E is the kinetic energy of the particle. As E is same for the particles, Hence Momentum is directly proportional to $$\sqrt{M}$$. As electron ha minimum mass among them, so momentum of electron is minimum. · 3 years, 5 months ago
