Two spheres of masses $$m$$ 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 3. The gravitational force will now be
A.
$$\frac{F}{3}$$
B.
$$\frac{F}{9}$$
C.
$$3F$$
D.
$$F$$
Answer :
$$F$$
Solution :
According to Newton's law of gravitation, the force between two spheres is given by,
$$F = \frac{{GMm}}{{{r^2}}}$$
From the relation, we can say the gravitational force does not depend on the medium between two spheres hence, it remains same, i.e. $$F.$$
