Moving Charges And Magnetism

Two charged particles $A$ and $B$ of masses $m$ and $2 m$, charges $2 q$ and $3 q$ respectively moving with same velocity enter a uniform magnetic field such that both the particles make same angle ( $<90^{\circ}$ ) with the direction of the magnetic field. Then, the ratio of pitches of the helical paths of the particles $A$ and $B$ is
