Ha, thanks Vincent I was overthinking it!

anonymous · Answer

Two ways to solve this.  First (which seems to be the way the author of the question intended) is to use the formula$$|F|=\frac{Gm_1m_2}{r^2}$$Or, alternately, you could find the force due to the known value of acceleration at the earth's surface$$|F|=|mg|=9.8(5)=49 N$$

You must close your question and open a new one. If you delete and replace it, the thread of answers does not make sense anymore, and people cannot use your original question to learn.
