- 9. Multiple Choice
An object has a mass of 50 kg.
The gravitational field strength on Earth is 10.0 N/kg.
The gravitational field strength on a distant planet is 4.0 N/kg.
What is the weight of the object on Earth, and what is its weight on the distant planet?
on Earth = 5.0 kg, on the distant planet = 12.5 kg
on Earth = 5.0 N, on the distant planet = 12.5 N
on Earth = 500 kg, on the distant planet = 200 kg
on Earth = 500 N, on the distant planet = 200 N
