360031 If there were a smaller gravitational effect which of the following forces do you think would alter in some respect?

1 Viscous forces
2 Archimedes uplift
3 Electrostatic
4 Magnetic

360032 Two spheres of mass \({m}\) and \({M}\) are situated in air and the gravitational force between them is '\({f}\)'. The space around the masses is now filled with a liquid of specific gravity 4. The gravitational force will now be

1 \({4 f}\)
2 \({f / 4}\)
3 \({f / 16}\)
4 \({f}\)
