Question

The distance between two objects is increased by 3 times the original distance. How will this change the force of attraction between the two objects? A. The new force will be 1 3 of the original. B. The new force will be 3 times more than the original. C. The new force will be 1 9 of the original. D. The new force will be 9 times more than the original.

Answer 1

Answer:

C.  

The new force will be 1 /9 of the original.

Answer 2

Answer:

C

Explanation:

The answer is 1/9 or C.

About the easiest way to figure this out is to take the force of gravity to be 1 Newton when G*m1*m2 = 1 and r = 1 meter.

Now if you change the distance to 3 meters then

G*m1*m2 still = 1

but R becomes 3

F = 1 / 3^2

F = 1/9
