True/False

1. A cyclotron operates with a given magnetic field and at agiven frequency. If R denotes the radius of the final orbit, the final particle energy is proportional to 1/R.

3. All charged particles which pass through crossed electric and magnetic fields without deflection have the same mass and momentum.
4. A uniform magnetic field is parallel to and in thedirection of the positive z axis. For an electron to enter thisfield and not be deflected by the field, the electron must be traveling along the z axis.
5. In a cyclotron, particles with the same charge-to-massratio have the same period of oscillations.
