7.Gravitation
easy
If $M$ the mass of the earth and $R$ its radius, the ratio of the gravitational acceleration and the gravitational constant is
A
$\frac{{{R^2}}}{M}$
B
$\frac{M}{{{R^2}}}$
C
$M{R^2}$
D
$\frac{M}{R}$
Solution
(b) Acceleration due to gravity $g = \frac{{GM}}{{{R^2}}}$
$\frac{g}{G} = \frac{M}{{{R^2}}}$
