"welcome to leto q a video i am vineeth your lido tutor bringing you this question on your screen ex describe how the gravitational force between objects and the distance between them now we know that the gravitational force between two objects is given by the product of their masses by the square of the distance between them therefore we can say that f is inversely proportional to the square of distance right now since the force is inversely proportional to the distance to the square of the distance so when the distance is doubled gravitational force becomes 1 by 4 and when distance is halved gravitational force becomes four times isn't that easy guys if you still have a doubt though please leave a comment below do like the video and subscribe to our channel i'll see you in our next video until then bye guys keep learning"
