Answer 1

GIVEN :-

• Mass = 5 kg
• Weight on Earth = 49 N
• Acceleration due to gravity on moon = 1/6 of that of Earth

Let :-

• Acceleration on Earth be a

Formula used :-

• Force = Mass x acceleration

Solution :-

We know that,

Force = mass x acceleration

so, Substituting the value we get,

$= > 49N = 5kg \times a \\ = > 5a = 49N \: \: \: \: \: \: \: \: \: \: \\ = > a = \frac{49}{5} = 9.8 \: \:$

Since , the acceleration on Earth is 9.8 m/s²

Therefore, acceleration on moon,

$= > \frac{9.8}{6} = 1.33 m/s ^{2}$

So, weight on moon,

$= > 5 \times 1.633 \\ = > 8.17N \: \: \: \: \:$

Hope the answer helps you.
