Alpha particles (charge = +2e, mass = 6.68 ×10-27 kg, e = 1.60 × 10-19 C) are accelerated in a cyclotron to a final orbit radius

Question

Alpha particles (charge = +2e, mass = 6.68 ×10-27 kg, e = 1.60 × 10-19 C) are accelerated in a cyclotron to a final orbit radius of 0.90 m. The magnetic field in the cyclotron is 0.30 T. The period of the circular motion of the alpha
particles is closest to
O 1.3 μs.
O 0.44 μs.
O 0.87 μs.
