                    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

    Correct Answer: D

    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.
