Question

If the distance between two particles is reduced to half, the gravitational attraction between them will be

Answer 1

F=KQ1Q2/r^2

If the distance between two charges decrease by half then the force will increase 4 times as force is inversely proportional to r^2

Answer 2

Answer:

If the distance between two objects is doubled the gravitational force between them

So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).
