It's time for some Physics dude!!!!! The relation F=m1*m2*G/r^2 is mind-blowing. But in Class IX I have not been granted the luck and that conception to know them according to my science tuition teacher. If you want me to explain you this relation, I can do that, but not the derivation. There are some diagrams in that proof, so I might try to post it along with this post at some later time or now.
