Question

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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

Okay , thanks

Answer 6

Wait but its not doubled ?

Answer 7

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

Answer 8

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

Answer 9

Post in the Physics section!
