Question

how does the gravitational force changes when distance is done half​

Answer 1

Answer:

According to the law of gravitation, the force of attraction acting between two bodies is given by, Thus, when the distance between the objects is reduced to half the gravitational force increases by four times the original force.

Answer 2

The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of thedistance between them. Hence, if distancebetween charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.
