Question

What does an astronaut of mass 100 kg weigh
a on Earth where the gravitational fi eld strength is
10 N/kg,
b on the Moon where the gravitational fi eld strength is
1.6 N/kg?

Answer 1

Answer:

Earth = 1000 kg

Moon = 160 kg

Explanation:

Earth has a gravitation force of 10 N/kg, so if the mass is 100, it would be attracted towards the Earth 10 times faster than it's actual mass. Therefore, the weight of the astronaut on Earth is 100 x 10 = 1000 kg.

Moon has a gravitation force of 1.6 N/kg, so if the mass is 100, it would be attracted towards the Earth 1.6 times faster than it's actual mass. Therefore, the weight of the astronaut on Earth is 100 x 1.6 = 160 kg.
