The mass of a hypothetical planet is 1/100 that of Earth and its radius is 1/4 that of Earth.If a person weighs 600 N on Earth, what would he weigh on this planet?

Question

Quizplus · Accepted Answer

The gravitational force is proportional to the mass of the planet and inversely proportional to the square of its radius. The weight on the new planet is (1/100) of Earth's mass divided by (1/4)^2 of Earth's radius, which simplifies to 1/16. Therefore, 600 N * 1/16 = 37.5 N. However, the correct calculation should be 600 N * (1/100) / (1/16) = 96 N.
