Answer 1

when distance between two objects is decreased by D times the gravitational force between them increase 4 times the value of D is?--2

Answer 2

If the distance between two objects is doubled the gravitational force becomes one fourth since,

F=G

Where R is the diatnce between the bodies .

So , if R

=2R , then

F

=G
