Question

What is the mass of the object from the previous question if we put it on the moon? The force of gravity on the moon is 1.62 m/s2.

Question 8 options:

3,515 N

2,197 kg

2,197 N

21,532 kg


An object has a weight of 21,532 N on Earth. What is the mass of the object?

Question 7 options:

211,013 kg


none of the above


2,197 kg


2,200 g

Answer 1

Question 7 :

W₀ = weight of object on earth = 21532 N

g₀ = acceleration due to gravity on earth = 9.8 m/s²

m₀ = mass on earth for the object = ?

weight of the object is given as

W₀ = m₀ g₀

m₀ = W₀ /g₀

inserting the values

m₀ = 21532/9.8

m₀ = 2197 kg

Question 8 :

mass is a constant thing and it does not change location to location, mass remains same everywhere. hence the mass of the object on the moon comes out to be same that on earth as 2197 kg
