 Suppose there is a correction term to Newton's law of universal gravitation

where the letters have their usual meaning  and are given in SI units and, in particular, r is the separation 
distance between the two masses m1 and m2 and A is some new constant of nature. Find the units of 
this constant A.

The given equation represents the modified form of the gravitational force between two masses, taking into account a cosmological parameter \(\Lambda\):

\[ F_g = \frac{G m_1 m_2}{r^2} e^{-r/\Lambda} \left( 1 + \frac{r}{\Lambda} \right) \]

Where:
- \( F_g \) is the gravitational force between the two masses.
- \( G \) is the gravitational constant.
- \( m_1 \) and \( m_2 \) are the masses of the two objects.
- \( r \) is the distance between the centers of the two masses.
- \( \Lambda \) is a parameter related to the cosmological constant or another scaling factor, modifying the standard Newtonian gravitational force.

In this formula:
1. The term \(\frac{G m_1 m_2}{r^2}\) represents the Newtonian gravitational force.
2. The exponential term \( e^{-r/\Lambda} \) introduces a damping factor that decreases the force exponentially over a distance \( \Lambda \).
3. The term \( \left( 1 + \frac{r}{\Lambda} \right) \) adjusts the force based on the ratio of the distance to the parameter \(\Lambda\).

This equation suggests that at large distances, much larger than \(\Lambda\), the gravitational force decreases more rapidly than predicted by Newton's law of gravitation. This can be seen as incorporating effects due to a cosmological constant or other large-scale structure influences.
