MCQ
In a cyclotron, a charged particle:
  • A
    Undergoes acceleration all the time.
  • B
    Speeds up between the dees because of the magnetic field.
  • C
    Speeds up in a dee.
  • D
    Slows down within a dee and speeds up between dees.
✓

Answer

  1. Undergoes acceleration all the time.

Solution:

In a cyclotron, a charged particle describes the circular path inside the dees & is accelerated while going from one dee to another due to the electric field.

While moving in the circular path, charged particles have centripetal acceleration which is provided by the magnetic force due to the magnetic field.

A charged particle undergoes acceleration all the time, inside the cyclotron.
