Ncert Exercises & Solutions

In a cyclotron, a charged particle:

1.	undergoes acceleration all the time.
2.	speeds up between the dees because of the magnetic field.
3.	speeds up in a dee.
4.	slows down within a dee and speeds up between dees.

(a) Hint: The acceleration, as well as velocity, is a vector quantity.

The charged particle undergoes acceleration as:

(i) speeds up between the dees because of the oscillating electric field and

(ii) speed remain the same inside the dees because of the magnetic field but direction undergoes change continuously.
