How is the radius of the resulting circular or helical path dependent on the particle's momentum (mv)?

Answer

Directly proportional.

The radius of curvature is directly proportional to the particle's momentum ($mv$) and inversely proportional to the magnetic field strength ($B$) and the charge ($q$). Scientists use this relationship to determine momentum.
