In a magnetic field the curvature of the path of a `beta`-particle is greater than that of an `alpha`-particle of the same speed. Explain why.

The radius of curvature of the path of a charged particle moving in a static uniform magnetic field is

The radius of curvature of the path of a charged particle moving in a static uniform magnetic field is

In a given electric field , the beta particle are deflected more than the alpha -particle in spin of the alpha - particle having a langer charge

alpha -particles and beta -particles

Statement 1: If a proton and an alpha -particle enter a uniform magnetic field perpendicularly with the same speed, the time period of revolution of alpha -particle is double than that of proton. Statement 2: In a magnetic field, the period of revolution of a charged particle is directly proportional to the mass of the particle and inversely proprotional to the charge of particle.

In a given magnetic field for the particle less of same velocities the curvature of the paths of
