Deflection in an electric field. The force on the $\alpha^{++}$ particle is twice that on the $\beta^-$ particle, but also the velocity of the $\alpha^{++}$ is much smaller, so it's easier to change direction. Note that the velocity in the radius equation is related to only the perpendicular velocity, which is where the circular motion occurs. The period of the charged particle going around a circle is calculated by using the given mass, charge, and magnetic field in the problem. Please visit this website to see the detailed answer. That is what creates the helical motion. An expression for the total electric and magnetic forces on a single particle is required to treat beam dynamics. What is the ratio of their circular paths?
