Gravitational force between two objects will depends on mass and distance between the two objects
It is given by the formula as
[tex]F = \frac{Gm_1m_2}{r^2}[/tex]
Now here we can say that it depends inversely on square of distance between two masses
now if force is 5000 N when two masses are at distance "r" from each other
so it is given as
[tex]5000 = \frac{Gm_1m_2}{r^2}[/tex]
similarly we can say that if distance is increased by 3 times then we will have
[tex]F = \frac{Gm_1m_2}{(3r)^2}[/tex]
now we will find the ratio of two forces
[tex]\frac{F}{5000} = \frac{1}{9}[/tex]
so now the new force will be given as
[tex]F = \frac{5000}{9} = 555.5 N[/tex]
