Three identical point objects each of mass `m` are placed at the vertices of an equilateral triange of side `l`. What is the gravitational potential at the centre of the equilateral triangle due to the point masses?

Explanation

To find the gravitational potential at the center of an equilateral triangle formed by three identical point masses, we can follow these steps:

### Step 1: Understand the Concept of Gravitational Potential
The gravitational potential \( V \) at a point due to a mass \( m \) is given by the formula:
\[ V = -\frac{Gm}{r} \]
where \( G \) is the gravitational constant, \( m \) is the mass, and \( r \) is the distance from the mass to the point where the potential is being calculated.
