An `alpha` particle and a proton are moving in the plane of a paper in a region where there is uniform, magnetic field directed normal to the plane. If two particels have equal linear momenta, what will be the ratio of the radii of their trajectories in the field ?

An alpha particle and a proton are moving in a region normal to a uniform magnetic field B. If two particles have equal linear momenta, what will be the ratio of the radii of their trajectories in the field?

An alpha particle and a proton particle are moving on the surface of a-paper. A uniform magnetic field is normal on the paper. If the linear momentum of those two particles.are same then what will be the ratio of radii of them?

An alpha - particle and a proton moving with the same kinetic energy enter a region of uniform magnetic field at right angles to the field . The ratio of the radii of the paths of alpha - particle to that of the proton is

A proton and an alpha- particle, moving with the same velocity, enter a uniform magnetic field, acting normal to the plane of their motion. The ratio of the radii of the circular paths descirbed by the proton and alpha -particle is
