Question

If $M$ is 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. $MR^{2}$
• D. $\frac{M}{R}$

Answer 1

Answer: (B)

Gravitational acceleration is given by
$g=\frac{G M}{R^{2}}$
where $G=$ gravitational constant
$\therefore \, \frac{g}{G}=\frac{M}{R^{2}}$
