Question

if M the mass of the earth and R it's radius.the ratio of the gravitational acceleration and the gravitational constant is​

Answer 1

Step-by-step explanation:

mg= GmM/R²

g/G=M/R²

hope you understand

Answer 2

$\frac{M}{ { R}^{2} }$

Mass of Earth = M

Radius of Earth= R

$gravitional \: force = \frac{g \times m1 \times m2}{ {r}^{2} } \\ f = \frac{g \times m \times m2}{ {r}^{2} } = \frac{g \times m}{ {r}^{2} } \: \: m2 \times g \times m2 \\ \frac{g}{g} = \frac{m}{ {r}^{2} }$
