Question

If acceleration due to gravity on earth is $10m/s^2$ then, the acceleration due to gravity on moon is :

• A. $16.6m{s}^{-2}$
• B. $60m{s}^{-2}$
• C. $10m{s}^{-2}$
• D. $1.66m{s}^{-2}$

Answer 1

The correct option is D

$1.66m{s}^{-2}$

Given that

Acceleration due to gravity on earth,$g_e=10m{s}^{-2}$

Formula used

$g_m=\frac{1}{6}{g}_e$

Where $g_m$= Acceleration due to gravity on the moon

Calculation for acceleration due to gravity on the moon

$$\begin{gathered} g_m=\frac{1}{6}{g}_m \\ {g}_m=\frac{10m{s}^{-2}}{6} \\ {g}_m=1.66m{s}^{-2} \end{gathered}$$

Thus, Acceleration due to gravity on the moon is $1.66m{s}^{-2}$.

Hence, option (d) is correct.
