                  How is the gravitational force between two point masses affected when they are dipped in water keeping die separation between them the same?

Answer:

                  \[F=\,\frac{G{{m}_{1}}{{m}_{2}}}{{{r}^{2}}}\]. F does not depend upon the nature of medium which \[{{m}_{1}}\] and \[{{m}_{2}}\] are placed. Therefore, gravitational force between two point masses will not be affected, when dipped in water.
