Question 208695
Let g = gravitational attraction force in terms of pounds between two masses.

Your equation is: g = k/d^2, where k is the constant of proportionality and d is our distance squared.

We know that g = 4.

We also know that 3 = d.

We first need to find k.

4 = k/(3)^2

4 = k/9

4*9 = k

36 = k

Now that we know k, we need to find g.

g = 36/(6)^2

g = 36/36

g = 1 pound.
