Question

Value of $g$ on moon is _________ of the value of $g$ on earth.

• A. One-third
• B. One-sixth
• C. One-fourth
• D. One-tenth

Answer 1

Answer: (B)

One-sixth

Weight$=mg$

(where $m=$mass and $g=$acceleration due to gravity)

Let the acceleration due to gravity on moon $=g_{moon}$

Acceleration due to gravity on earth $=g_{earth}$

We know,

Weight of an object on moon$=\frac{1}{6}\times$weight of the object on earth

$m{g}_{moon}=\frac{1}{6}\times m{g}_{earth}$

$g_{moon}=\frac{1}{6}\times g_{earth}$
