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 Newton's law of gravitation, which states that the gravitational force \( F \) between two masses \( m_1 \) and \( m_2 \) separated by a distance \( r \) is given by the formula:

\[ F = G \frac{m_1 m_2}{r^2} \]

where \( G \) is the universal gravitational constant.
