Question

In a cyclotron, the particle is accelerated:
  1. A
    In the D-shaped magnets
  2. B
    In the gap between the dees by the alternating electric field
    Correct
  3. C
    By the static magnetic field
  4. D
    By centripetal force

Correct answer

In the gap between the dees by the alternating electric field

Explanation

The magnetic field keeps the particle in a semicircular path inside each dee; the alternating electric field in the gap between the dees does work and accelerates the particle each crossing.
