### Physics

An alpha particle and a proton are moving in the plane of the paper in a region where there is a unifom magentic field
(B in vector notaion ) directed normal to the plane of the paper. If the two particles have equal linear momenta, what will be the ratioof the radii of their trajectories in the field?

### Re: Physics

R_alpha/R_p=q_p/q_alpha, R are the radii and q are the charges of the particles.

The limit operator is just an excuse for doing something you know you can't.

### Re: Physics

Thanks for the quick reply however that is not what I am getting. For the ratio, I am getting 2:1.
