Two particles, an -particle and a -particle, are travelling through a uniform magnetic field. They

Question:

Two particles, an α-particle and a β⁻-particle, are travelling through a uniform magnetic field. They have the same speed and their velocities are at right
angles to the field. Determine the ratio of:
a. The mass of the α-particle to the mass of the β⁻-particle
b. The charge of the α-particle to the charge of the β⁻-particle
c. The force on the α-particle to the force on the β⁻-particle
d. The radius of the α-particle’s orbit to the radius of the β⁻-particle’s orbit.
