Two spacecraft in outer space attract each other with a force of 4 N. What would the attractive force be if they were one-eighth as far apart?

3 answers

gravitational force follows an inverse-square relationship

inverse of 1/8 is 8
... 8 squared is 64

Never mind Scott, I see my mistake. I forgot to do the last step ( multiply). Thank you for your help!
