A metal rign of mass m and radius R is placed on a smooth horizontal table and is set rotating abut its own axis in such a way that each part of the ring moves with a speed v. Find the tension in the ring.

Explanation

To find the tension in a rotating metal ring of mass \( m \) and radius \( R \) where each part of the ring moves with speed \( v \), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the System**:
- We have a metal ring of mass \( m \) and radius \( R \) rotating about its own axis. Each part of the ring moves with a speed \( v \).

2. **Consider a Small Segment of the Ring**:
