Question

A body weighs $60N$ on Earth. What will be its weight on the moon if the acceleration due to gravity on Moon's surface is $\frac{g}{6}$? $\text{Take}g=10m{s}^{-2}$

• A. $10N$
• B. $60N$
• C. $40N$
• D. $20N$
  

Answer 1

The correct option is A

$10N$

We know, weight of a body, $W=mg$
where $m$ is the mass of the body and $g$ is the acceleration gue to gravity.
So, $mg=60N$
$\Rightarrow m=\frac{60}{g}$.
Now calculating weight of the body on moon :
$W_m=m\times g_m$, where $g_m$ is the acceleration due to gravity on moon.
$g_m=\frac{g}{6}$
$\therefore W_m=m\times \frac{g}{6}$
$\Rightarrow W_m=\frac{60}{g}\times \frac{g}{6}$
$\Rightarrow W_m=10N$
