Question

On the earth, the gravitational field strength is 10 N/kg. On the moon, the gravitational field strength is 1.6N/kg. If an object has a weight of 50N on Earth, what is its weight on the Moon?

Answer 1

any where in the universe mass remains same..so first find mass..
weight on earth = m×g
50 = m×g
m = 50/10 = 5 kg...
this mass is same in moon
so weight of object on moon ...is
mass × gravitational field on moon
= 5 x 1.6 = 8N ans..

Answer 2

Answer :

Given -

• Weight of the object on earth = 50 N
• The gravitational field strength on earth = 10 N/kg
• The gravitational field strength on moon = 1.6 N/kg

To Find -

• Weight on the moon ?

Solution -

We know that, Weight = Mass*Gravitational force.

Weight on earth :

⇒ 50 = Mass*10

⇒ Mass = 50/10

⇒ Mass = 5 kg

Now, Weight on moon :

⇒ Weight = 5*1.6

⇒ Weight = 8 N

Hence, Weight of the object on moon is 8 N.
