Particle 1 and particle 2 have masses of m₁ = 1.6 10^-8 kg and m₂ = 4.4 10^-8 kg, but they carry the same charge q. The two particles accelerate from rest through the same electric potential difference V and enter the same magnetic field, which has a magnitude B. The particles travel perpendicular to the magnetic field on circular paths. The radius of the circular path for particle 1 is r₁ = 8 cm. What is the radius (in cm) of the circular path for particle 2?
