Question

What is the value of acceleration due to gravity on the moon?

($g$ is the acceleration due to gravity on the Earth)

• A. $\frac{g}{4}$
• B. $\frac{g}{5}$
• C. $\frac{g}{6}$
• D. 0

Answer 1

The correct option is C

$\frac{g}{6}$

Since on the Earth, $g=\frac{GM}{R^2}$​
Similarly for the moon, $g_{moon}=\frac{G{M}_{moon}}{{\left(R_{moon}\right)}^2}$​
$M_{moon}$ ​and $R_{moon}$​ are the mass and radius of the moon respectively
Now, after putting the actual values of the masses and radii values we get:
$\frac{g}{g_m}=6$
