## Homework Statement

On earth, two parts of a space probe weigh 11 000 N and 3400 N. These parts are separated by a center-to-center distance of 12 m and may be treated as uniform spherical objects. Find the magnitude of the gravitational force that each part exerts on the other out in space, far from any other objects.

## Homework Equations

Fg = Gm1m2/r^2

## The Attempt at a Solution

I have a homework sheet that the professor gives out to help us. In his answer he has m1 = 7.2kg and m2 = .38kg

How did he get this?

I get 1123.4 and 346.9

Also how did he find that r1 = .11m and 42 = .028m??
