Answer:
<em>If the distance doubles, the gravitational force is divided by 4</em>
Explanation:
<u>Newton’s Universal Law of Gravitation </u>
Objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance.
Where:
m1 = mass of object 1
m2 = mass of object 2
r = distance between the objects' center of masses
G = gravitational constant: 6.67\cdot 10^{-11}~Nw*m^2/Kg^2
If the distance between the interacting objects doubles to 2r, the new force F' is:
Operating:
Substituting the original value of F:
If the distance doubles, the gravitational force is divided by 4
