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?

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

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

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
