Question

by how much will the gravitational force change,if

distance between the interacting object is reduced by its half​

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 2×21.

That is, 1/4.

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

Answer 2

Answer:

How does the force of gravitation between two objects change when the distance is reduced to half?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
