An 12 kg mass and a 18 kg mass experience a force of gravity pulling the balls towards each other of 4.7 x 10^-10 N. What is the separation distance of the two masses?

Explanation:

We can use Newton's Universal Law of Gravitation to solve this:

,

Plugging in given values, we have the equation:

.

Solving, we get:

.
