The reason for less deflection of the alpha particle than beta particle in the magnetic field.
Explanation of Solution
Introduction:
The deflection of the particle depends on the mass and speed of the particle.
The alpha particle contains the two protons and beta particles contain one electron. The mass of the proton is more than the mass of electron. The speed of the electron is very high than the speed of the proton.
The electrons pass from magnetic field with very high speed than the speed of proton. The magnetic force on beta particles is less than the magnetic force on alpha particle So, the alpha particles deflect more than the beta particle in the magnetic field.
Conclusion:
Thus, the alpha particle deflects more than the beta particles in magnetic field because the alpha particle is heavier and slower than the beta particles.
