If two charged particles each of charge q mass m are connected to the ends of a rigid massless rod and is rotated about an axis passing through the centre and `bot` to length. Then find the ratio of magnetic moment to angular momentum

Explanation

To find the ratio of magnetic moment to angular momentum for two charged particles connected to a rigid massless rod and rotating about an axis through the center, we can follow these steps:

### Step 1: Define the System
Consider two charged particles, each with charge \( q \) and mass \( m \), connected at the ends of a rigid massless rod of length \( 2r \). The system rotates about an axis perpendicular to the length of the rod and passing through its center.

### Step 2: Calculate the Moment of Inertia
The moment of inertia \( I \) for the two particles can be calculated as follows:
- Each particle is at a distance \( r \) from the center.
