An a - particle and a proton are moving in a plane of paper in a region where there is uniform magnetic field (B)  directed normal to the plane of the paper. If the two particles have equal linear momentum, what will be the ratio of the radii of their trajectories in the field?

Expert Answer:

Radius of the charged particle in a uniform magnetic field(r)=mv/qB=P/qB-------(1)
As the momentum and magnetic field is same the radius will depend on the charges of the particles .
