Question

Mass of an object on earth is 60kg. What will be its mass and weight on moon?​

Answer 1

Mass of an object on earth is 60Kg = It's mass on the moon will be 78N

Answer 2

Given:

Mass of object on Earth = 60kg

To Find:

1. Mass of the same object on moon
2. Mass of the weight of the object on moon

Method:

• We know that mass of the object does not change and remains same everywhere.

Therefore,

Since mass of the object on Earth = 60kg

So, mass of the object on moon = 60kg

To find:

Weight of the object on Earth and Moon

• We know that weight is a force

Force = mass × acceleration

Here,

the force is 'weight', and accceleration is 'acceleration due to gravity (g)'

So,

Weight = mass × acceleration due to gravity

OR

W = m × g

Mass on Earth = 60kg

Acceleartion due to gravity on Earth = 9.8m/s²

So,

Weight on earth = 60 × 9.8

= 588 N

Now,

• We know that weight of the object on moon is 1/6 on that of the earth

Hence,

Weight of the object on moon = Weight of object on Earth ÷ 6

⇒ 588/6 = 98 N

Answer:

∴ Mass of the boject on Moon = 60 kg

∴ Weight of object on Earth = 588 N

∴ Weight of object on moon = 98 N
