consider a nonconducting ring of radius r and mass m which has a total charge q distributed uniformly on it the ring is rotated about its axis with an angular speed `omega`. (a) Find the equivalent electric current in the ring (b) find the magnetic moment `mu` of the . (c) show that`mu=(q)/(2m)` where l is the angular momentum of the ring about its axis of rotation.

Explanation

To solve the problem step by step, we will address each part of the question systematically.

### Part (a): Find the equivalent electric current in the ring.

1. **Understanding the Concept of Current**:
The equivalent electric current \( I \) in a rotating charged ring can be defined as the total charge \( q \) passing a point in the ring per unit time.

2. **Finding the Time Period**:
