A deuteron, with the same charge but twice the mass of a proton, moves with a speed of 6.0  105 m/s perpendicular to a uniform magnetic field of 0.20 T. Which of the paths described below would it follow? (qp = 1.6  10-19 C and md = 3.34  10-27 kg)
 a. a circular path of 6.3-cm radius
  c. a circular path of 3.1-cm radius
  b. a circular path of 1.6-cm radius
  d. a straight line path
