How does the force of gravitation between two objects change when the distance between them is reduced to half ?

Explanation

To determine how the force of gravitation between two objects changes when the distance between them is reduced to half, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Universal Law of Gravitation**:
The gravitational force \( F \) between two objects of masses \( m_1 \) and \( m_2 \) separated by a distance \( r \) is given by the formula:
\[
F = \frac{G \cdot m_1 \cdot m_2}{r^2}
