**Gravitational Force Calculation**

The formula for the gravitational force (\( F_g \)) between two masses (\( m_1 \) and \( m_2 \)) separated by a distance (\( r \)) is given by:

\[
F_g = \frac{Gm_1m_2}{r^2}
\]

Where:
- \( F_g \) is the gravitational force.
- \( G \) is the gravitational constant.
- \( m_1 \) and \( m_2 \) are the masses.
- \( r \) is the distance between the centers of the two masses.

**Question:**

Two masses, \( m_1 \) and \( m_2 \), are separated by a distance, \( r \). The force of attraction between the two masses is \( F \).
If \( r \) is halved, how would \( F \) change?

**Options:**

- ○ \( 4F \) (4 times the force)
- ○ \( 1/4F \) (1/4 times the force)
- ○ \( 2F \) (2 times the force)
- ○ \( 1/2F \) (1/2 the force)
