Describe the motion of a charged particle in a cyclotron if the frequency of the radio frequency `(rf)` field were doubled.

Explanation

To describe the motion of a charged particle in a cyclotron when the frequency of the radio frequency (rf) field is doubled, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Cyclotron**:
A cyclotron consists of two D-shaped electrodes (dees) placed in a magnetic field. A charged particle moves in a semicircular path within these dees due to the magnetic field.

**Hint**: Remember that the motion of the charged particle is influenced by both the magnetic field and the electric field created by the rf source.
