Question

Two spheres of masses m and M are in air with gravitational force F between them. The space around the masses is filled with a liquid of specific gravity 3. What is the new gravitational force?

G1 Physics · Accepted Answer

Step 1: Newtonian gravity is F=GMm/r² and does not depend on the dielectric or density of the surrounding medium. Step 2: The mutual gravitational force is unchanged, F. Final answer: B — F.
