65. In the figure below, a uniform magnetic field is perpendicular to the page and two particles with electric charges $q_1$ and $q_2$ move under the influence of this field as shown. If the mass and speed of the two particles are equal, which of the following is correct?
[Figure: Uniform magnetic field directed out of the page; particle (1) moves in a larger circular arc and particle (2) moves in a smaller circular arc]
  • [(1)] $|q_1| > |q_2|$ and $q_2 < 0$
  • [(2)] $|q_1| > |q_2|$ and $q_1 < 0$
  • [(3)] $|q_1| < |q_2|$ and $q_1 < 0$
  • [(4)] $|q_1| < |q_2|$ and $q_2 < 0$
