Question

As per Newton's universal law,If the distance is doubled ,the force decreases by a factor of ______.

1)double
2)4
3)2
4)5​

Answer 1

Answer:

The gravitational force between two objects is inversely proportional to the square of distance between them.

So, if the distance between two objects is doubled, then the gravitational force becomes

1/ 2×2.

That is, 1/4.

Therefore, if the distance between two masses be doubled, then the force between will becomes 1/4.
