How is the gravitational force between two masses affected if the separation between them is doubled ?

Explanation

To determine how the gravitational force between two masses is affected when the separation between them is doubled, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Gravitational Force Formula**:
The gravitational force \( F \) between two masses \( m_1 \) and \( m_2 \) separated by a distance \( r \) is given by Newton's law of gravitation:
\[
F = \frac{G \cdot m_1 \cdot m_2}{r^2}
