I come across this formula :(adsbygoogle = window.adsbygoogle || []).push({});

g-g'=(2h/R)g ; h<R

However , if I substitute h =3R/4 the change in gravitational will be 1.5g .

How can the change of gravitational field strength is bigger than its original gravitaitonal field strength ?

Besides , how can I prove F=GMm/R2 ?

Besides this , where can I find the details explanation on gravitational
