Find potential at a point 'P' at a distance 'x' on the axis away from centre of a uniform ring of mass `M` and radius `R` .

Explanation

To find the gravitational potential \( V \) at a point \( P \) located at a distance \( x \) along the axis of a uniform ring of mass \( M \) and radius \( R \), we can follow these steps:

### Step 1: Understand the Geometry
Consider a uniform ring of mass \( M \) and radius \( R \). The point \( P \) is located along the axis of the ring at a distance \( x \) from the center of the ring. The distance from any point on the ring to point \( P \) can be represented as \( l \), which can be calculated using the Pythagorean theorem:
\[ l = \sqrt{R^2 + x^2} \]
