Question

The mass of an object is 15 kg. What will be the weight of it on moon ?​

Answer 1

Given,

The mass of an object is = 15 kg

To Find,

The weight of it on Moon =?

Solution,

We can solve the question using the following steps:

The weight of an object, $W = mg$

Here, $m =$ Mass of the object

          $g =$ Acceleration due to gravity

Weight on the object on Earth, $W_{e} = 15*10$     (Taking $g = 10m/s^{2}$)

                                                     $W_{e} = 150 N$

Now, the acceleration due to gravity on Moon is 1/6th the acceleration due to gravity on Earth.

$g_{m} = \frac{1}{6} g$

$g_{m} =\frac{10}{6}$

Weight on the object on the moon, $W_{m} = mg_{m}$

                                                            $W_{m} =15*\frac{10}{6} = 25 N$

Hence, the weight of the object on the Moon is 25 N.

Answer 2

Given,

Mass of an object=15kg

To Find,

Its weight on moon.

Solution,

We know that the weight of an object on the earth is different from its weight on the moon.

So, its weight on the earth=mass of that object× acceleration due to gravity(g=10m/s²)

Then, it will be 15kg×10m/s²=150Newton(on the earth surface)

weight on the moon=1/6×weight on the earth

So, here weight on the moon will be 1/6×150=25 Newton.

Hence, the weight of the object on the moon will be 25 Newton.
