A particle moves in a circle of radius 4 m with a linear velocity of `20ms^(-1)`. Find the angular velocity.

Explanation

To find the angular velocity of a particle moving in a circle, we can use the relationship between linear velocity (v), angular velocity (ω), and radius (R) of the circle. The formula that relates these quantities is:

\[ v = \omega R \]

### Step-by-step Solution:

1. **Identify the Given Values:**
- Radius of the circle, \( R = 4 \, \text{m} \)
