Six point masses of mass `m` each are at the vertices of a regular hexagon of side `l`. Calculate the force on any of the masses.

Explanation

To solve the problem of calculating the gravitational force on any of the masses located at the vertices of a regular hexagon, we can follow these steps:

### Step 1: Understand the Configuration
We have six point masses, each of mass \( m \), positioned at the vertices of a regular hexagon with side length \( l \). We need to calculate the net gravitational force acting on one of these masses due to the other five masses.

### Step 2: Calculate the Gravitational Force Between Two Masses
The gravitational force \( F \) between any two point masses \( m \) separated by a distance \( r \) is given by Newton's law of gravitation:
\[
