7.Gravitation
normal
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 between bodies will now be
A
$F$
B
$\frac {F}{3}$
C
$\frac {F}{9}$
D
$3F$
Solution
According to Newton's law of gravitation, the force between two spheres is given by $F=\frac{G M m}{r^{2}}$ From the relation, we can say that the gravitational force does not
depend on the medium between two spheres hence, it remains same ie, F.
