Question

Object a attacks object b with a gravitational force of 5 Newton’s from a given distance between the two objects is reduced in half, what will be he changed force of attraction between them?

Answer 1

answer is D. 20 newtons for plato users, got 100 on the test :)

Answer 2

Since gravitational force decreases by distance squared, if you double the distance you get Sqrt the force, and if you half the distance the force becomes squared.

Should be 25N
