Question

suppose the gravitational potential due to a small system is k/rsqare at a distance r from it​

Answer 1

Answer:

V∝ $\frac{K}{r{2} }$

compare with gravitational potential

$v_{g}$ ∝ $\frac{1}{r\\}$

$F_{g}$∝$\frac{1}{r^{2} }$

$F$∝ $\frac{k}{r^{3} }$

If there is negative mass then attraction occurs..If there were negative masses, then this type of system is possible.

This system is a dipole of two masses, i.e., two masses, one positive and the other negative, separated by a small distance.

In this case, the gradational field due to the dipole is proportional to 1/r^3.
