Question

If the mass of an object on the earth is 65kg. Then what is the weight of the object on moon.

Answer 1

Answer: 10.8 kg

Answer 2

Given:

Mass of object on earth (M) = 65 kg

To find:

Weight of object on moon.

Solution:

• We know, an attractive force called Gravitational Force that is responsible or helpful for us in maintaining our posture and making us able to stand firmly on the ground.

• Unlike in space, where we know the gravitational force between 2 foreign bodies is so less as compared to on earth, that astronauts living there cannot remain standing at a position and keep floating in the space.  

We know, on the moon, the acceleration due to gravity or the force of gravity is $\frac{1}{6}$ times the gravity on earth.

Hence,

Value of g on moon $=\frac{1}{6}$ $of$ $9.8$  ; that is

$g_{m}=1.634m/s^{2}$  

Hence,

Weight of the object on the moon $W_{m}=M g_{m}$

Substituting the given values in the equation, we get

$W=(65)(1.634)$

$or$

$W=106.21 kg$  

Final answer:

Hence, the weight of the object of mass 65 kg(on earth) on the moon will be 106.2 kg.
