Question

The weight of a man on the earth is 100 N. What is the mass and weight of the man on

moon? (g=10m/sec2

) ​

Answer 1

Answer:

Weight on earth = 600N

Let g= 10m/s

2

on earth

Mass on earth =

10

600

=60 kg

Now, since mass is a constant quantity so, it will remain 60 kg on the moon also.

Now, weight on moon = mg

′

m= mass =60 kg

g

′

= acc. due to gravity on moon =

th

the value on earth

So, Weight on moon =

th

of the weight on earth

⇒ Weight on the moon =600×

1

=100 N

Answer 2

Answer:

weight on the moon is 16.667N

Explanation:

As the weight of a man on the earth is 100N so,

W=100N

W=mg

mg=100

m=100/g

as g=10m/s^2

m=10 kg

The value of gravity on moon is 1/6 times that on the surface of earth

g'=1/6g

as g=10m/sec^2 so g'=1.667m/sec^2

the mass of the man on the moon is same as on the earth as it is constant at any place.

the weight of man on the moon is W'=mg'=(10)(1.667)=16.667N
