What happens to the gravitional force between two objects if the distance between them doubles ?

Question

anonymous · Answer

it is reduced. it depends on their respective masses by how much it is reduced.

anonymous · Answer

reduced by 4 times
as force is inversly proportional to square of the distance

anonymous · Answer

Does the force increase by a factor of four or does it reduce by half

anonymous · Answer

force is reduced by a factor of 4
since tha equation is$$F=Gm _{1}m _{2}/r ^{2}$$

anonymous · Answer

Okay , thanks

anonymous · Answer

Wait but its not doubled ?

anonymous · Answer

ya as said above $$F   \alpha 1/r ^{2}$$ so $$F _{1}/F _{2}=r _{2}^{2}/r _{1}^{2}$$
when $$r _{1}=r,r _{2}=2r  and   F _{1}=F then F _{2} becomes F/4$$

anonymous · Answer

Im only in 7th grade...and Ok ? I guess But I dont understand F1 /F2 ??
