On earth, two parts of a space probe weigh 12000 N and 7900 N.

These parts are separated by a center-to-center distance of 22 m and

may be treated as uniform spherical objects.

Now, find the magnitude of the gravitational force that each part exerts on the other out in space, far from any other objects.

in Newtons

i know there is an equation for this:

and also one force will be in the positive directiona and the other in the negative.

need help.
