If the distance between two objects is doubled, what happens to the
gravitational force between them?
A. It decreases to 1/2 its original magnitude.
B. It increases to 2 times its original magnitude.
C. It increases to 4 times its original magnitude.
D. It decreases to 1/4 its original magnitude.

Answer 1

D

Step-by-step explanation:

F = G m1 m2 / r^2 now double r

F = G m1m1/ (2r)^2

F = 1/4 G m1m2/r^2 <===== this is 1/4 of the original
