this question is simple, I was looking for a good derivation to Gauss' Law of gravitation $$\int \vec g.d\vec A=-4\pi GM $$ but was unable to find a good enough one online. Hence may I know its derivation?

1Its identical to the Electrostatic derivation, if you swap $ 1/4 \pi \epsilon_0 $ for G, and take into account that positive mass is analogous to negative charge when it comes to the direction of the force. – Johnny Aug 09 '20 at 09:36

@JohnyO42 i will check out the electrostatic derivation, thank you! – Lucas Tan Aug 09 '20 at 10:10
