It requires understanding the relationship between the Lorentz force acting on a charged particle, the radius of its circular path, and its mass. Given the Lorentz factor, magnetic field strength, and radius of the path, the objective is to calculate the mass of the particles. The solution involves applying the relevant equations to derive the mass from the provided information."}
