    A 20 kg sphere is at the origin and a 10 kg sphere is at (x,y) = (20,0

    Okay, now I'm lost again. If I don't need to know what G is then what equation should I be using?

    A 20 kg sphere is at the origin and a 10 kg sphere is at (x,y) = (20,0

    Thank you very much! What does G equal? And for the radius would I divide the distance by 2?

    A 20 kg sphere is at the origin and a 10 kg sphere is at (x,y) = (20,0

    Thank you! How would I go about plugging my information into the equation? I'm extremely new to physics and the textbook lacks information on solving this problem
