Question

Derive the relation between universal gravitational constant and acceleration due to gravity

Answer 1

Ur ans is in this pic.......Check relation between g and G .....

Answer 2

Gravitational force is given by
F = GMm/r^2

Here F = ma = mg

Therefore,
mg = GMm/r^2
Divide both sides by m
g = GM / r^2

In above g and G relation
g = acceleration due to gravity of planet
G = universal gravitational constant
M = mass of planet
r = radius of planet
