Suppose the gravitational potential due to a small system is k/r 2 at a distance r from it. What will be the gradational field? Can you think of any such system? What happens if there were negative masses?

The gravitational field is given as the negative of potential gradient.

Here,

We know that gravitational force, from experiments. Hence, this type of system is not possible.

However, in case of dipoles, the electric field can vary as . thus, if there was a concept of negative mass, this law could be valid.
