If the masses of two bodies are quadrupled and the distance between their centres is doubled, then how many times the force of gravitation between them will be changed ?

Explanation

To solve the problem, we will use the formula for gravitational force and analyze how changes in mass and distance affect this force.

### Step-by-Step Solution:

1. **Write the formula for gravitational force**:
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}
