Two neutral bodies of masses \(m_1\) and \(m_2\) are kept at a distance of r cm from one another in a vacuum medium. A gravitational force \(F_v\) acts between the two bodies. The entire set-up is then transferred, as it is, to a water medium. The force between the bodies is then \(F_w\). The ratio of \(F_v\) to \(F_w\) is:
