The force between two objects decreases by 36% when the distance between them is increased by 4 m. Find the original distance between them.

Explanation

To solve the problem, we will use the formula for gravitational force and the information given about the change in force when the distance is increased.

### Step-by-Step Solution:

1. **Understand the Problem**:
We know that the gravitational force \( F \) between two masses \( m_1 \) and \( m_2 \) separated by a distance \( r \) is given by:
\[
F = \frac{G m_1 m_2}{r^2}
