Space rover weighs 100 N on Earth while a different space rover weighs 100 N on the moon

When you compare the masses of the two space rovers, which rover has the greater mass?

The second rover has a greater mass.

Explanation:

Given data,

The weight of the space rover on earth, W = 100 N

W = mg

m = W / g

= 100 / 9.8

= 10.2 kg

Hence, the mass of the space rover on earth is, m = 10.2 kg

The weight of the different space rover on moon W' = 100 N

W' = mg'

m = W'/g'

= 100 / 1.6 (acceleration due to gravity on moon g' = 1.6, m/s²)

m = 62.5 kg

Hence, the second rover has a greater mass.
